I don't think there is any way to do that. The ability to RMB on a body and choose "Component Line Font" similar to the present functionality for parts would make a nice enhancement request.
I think that there is an alternate position view that you might be able to use. It lays one view on top of another.
Good shout but alternate position view doesn't work for parts, only assemblies. But based on your suggestion, I tried overlaying and aligning two separate views by origin (vertically and horizontally). One view with everything in one line font (phantom) and the other with solid line font. I think this would work, but for some reason the alignment is off (even though I've double-checked it in the part).
Find one workaround and create a new problem!!!
Thanks for the input.
