convert points to same utm zone

I have lat/long and when I convert to UTM, my points are in zones 35 and 36. is it possible to "transform" or "project" (I am not sure which word is used to do this operation) the UTM coordinates from zone 36 to zone 35 ?

Edit: Just to clarify I have those two coordinates.

point 1: is in 35L 460880.04 E 8327740.29 S
point 2: is in 36L 201956.55 E 8375498.52 S

is there any way to say: point 2 is in 35L xxxxxxx E yyyyyy S ?
