Linking .rui files w/toolbars having same names as ones in default lib

I am doing some more experiments in view of customizing my V8 workspace. In the past I ran into trouble with Rhino getting confused between toolbars in the default library and the ones in a linked.rui if they had the same name. Since the modified toolbars I am bring in are from V7 and they originally started out life as standard toolbars, they have mostly the same names as ones in V8’s default library. Should I be changing those names before attempting to link/import?

Also, how do I copy a tool button say from an imported (linked) .rui to the default library? Does the old copy button procedure do that?
