adding crown moulding to multiple cabinets

[Elovia]

I don't have Interior Designer, so you'll have to forgive my ignorance.

Can you select a cabinet, and then hold down the shift button and select a second cabinet? If so, can you then open the cabinet specification dialog and assign molding?

If not the above, do you have many of the same type of cabinet? You could apply molding to one and then copy-paste the rest. I'm not sure if ID9 has the copy/transform tool, but that would work well for creating and placing multiple copies, if you do.

Just throwing out suggestions to explore.
