AutoCAD Inventor :: Copy Colors Of Surfaces With Mirror / Array Command?

I have an ipart I'd like to create w/ surfaces.  The surface color is important because we use that as plate thickness ID in FEA.  When I color a surface blue, then another red I continually get the default color when using the mirror or array command.  We're creating a customizeable ipart where there will be some intelligence surrounding how big the array (we may need 3, 4, or 5 beams based on the unit size).  I need a way that the colors on the surface propogate to the new surfaces created by the commands.
