I think I understand what you mean when you said that I can overlap uvs, I just need to uv map everything, and then put the uvs to overlap ontop of eachother in the UV map editor screen (but I would have already had to individually uv map each section, this case each face and then place them overlapping). Did I understand you correctly? I hope so. Thanks a lot for the help guys.

You mentioned also that I could assign the file just to the faces I want, how would I go about doing that?
