Currently part view reps can control part appearances, but they only affect every face of the part.
I would like them to respect the face appearance overrides that I assign too.
An example: Color the inside of a sheetmetal electrical enclosure white and the outside some other set of colors. Then use the part view rep to control the enclosure color in an upper level assembly
