Showing different colors for different members in weldment drawing

I know you can assign visual properties to different members in the actual model, but is there a way to show different colors for the different members in the drawing?  The reason I ask, is because I have both square tubing and L-angle in the same weldment, and would like to make it more obvious which is which on the print for our welders...  I know you can do it for parts in an assembly, but I can't figure out how to do it for a weldment...if it's even possible at all.  If not, it should be!
