Oracle / GeoServer / WFS-T / Openlayers many polygons as one feature

Newbie question regarding Oracle / GeoServer / WFS-T / Openlayers. I am creating a table that will hold geometry features a user creates/updates. My question is, I would like to have just one record in the table per customer (customerId). Can I create many polygons/points/lines as one feature in OpenLayers and have that go to GeoServer/WFS-T as one feature that then gets written all in one record in the Oracle Table? Currently I have it all running but it is creating one record for each feature.

One more thing to note, Oracle does allow this by setting the SDO_GTYPE (geometry type) as a MULTIPOLYGON (2007). The questions is how to create multiple features as one record in OpenLayers/ WFS-T / GeoServer. Is there a setting in the Editable Layer I am missing? Thanks.

Here is my editable layer:

var saveStrategy = new OpenLayers.Strategy.Save();

        customers = new OpenLayers.Layer.Vector("Customers", {
            strategies: [new OpenLayers.Strategy.BBOX(), saveStrategy],
            projection: new OpenLayers.Projection("EPSG:2236"),
            protocol: new OpenLayers.Protocol.WFS({
                version: "1.1.0",
                srsName: "EPSG:2236",
                url: "http://server01:8085/geoserver/sf/wfs",
                featurePrefix: "sf",
                featureType: "customers",
                featureNS: "http://a.org/layers01",
                geometryName: "GEOMETRY"
            })
        });

This is the feature added method:

function FeatureAdded(object)
        {

            var added_feature = object.feature;
            added_feature.state = OpenLayers.State.INSERT;

            // Setup Customer Id for inserting to one record
            // NOTE: This is not working, it just creates multiple records
            //       with the next id number (seed)
            added_feature.attributes.customerId = 123456;

            saveStrategy.save();

        }

When I set the strategy to OpenLayers.Strategy.BBOX(), I get multiple records created in the table. (I am looking to create just one MultiPolygon record in the table.) When I set the strategy to OpenLayers.Strategy.Fixed(), I get no client error (fail method for the strategy does not fire), no GeoServer log error and no records written to the table.

Update # 1

As requested, here is a sample post request. In this case I created two polygons which I only wanted to be one record, but it created two records in the table:

Update # 2

I tried removing all features and replacing them as one mpolygon:

// Add Polygons to a MultiPolygon 
            function cmd_Poly_add()
            {

                var features = customers.features;

                var polygons = [];
                var f = null;

                for (f in features)
                {
                    polygons.push(features[f].geometry);
                }

                var myCombinedFeature = new OpenLayers.Feature.Vector(new OpenLayers.Geometry.MultiPolygon(polygons));
                myCombinedFeature.state = OpenLayers.State.INSERT;
                customers.removeFeatures(features);
                customers.addFeatures([myCombinedFeature]);
                customers.redraw();

            }



function FeatureAdded(object)
{

cmd_Poly_add()

}

I then checked the wfs transaction being sent but when I perform the above, the data is getting removed from the body of the wfs:insert.

The original node goes to this level:

 <wfs:Insert>
  <feature:CUSTOMERS xmlns:feature="http://a.org/layers01">
    <feature:GEOMETRY>
      <gml:MultiSurface xmlns:gml="http://ift.tt/WaETtx" srsName="EPSG:2236">
        <gml:surfaceMember>
          <gml:Polygon>
            <gml:exterior>
              <gml:LinearRing>
                <gml:posList>

Once I create the new polygon with the line:

customers.addFeatures([myCombinedFeature]);

Everything is gone and only creates a transaction to this level:

<wfs:Insert>
  <feature:CUSTOMERS xmlns:feature="http://a.org/layers01">
    <feature:GEOMETRY>
      <gml:MultiSurface xmlns:gml="http://ift.tt/WaETtx" srsName="EPSG:2236">

And I can see it going into the loop and adding the features:

... for (f in features) { polygons.push(features[f].geometry); } ...

To the multipolygon but the transaction is empty as shown above.
