Adding crown molding to a cabinet style hood

[KBEDesign]

Is there an easier trick to adding crown molding to a cabinet hood from a catalog? I have used the molding polylines in the past but find it tedious and it never quiet merges correctly with the cabinets on either side. Just wondering if I'm missing something, I've tried copying my moldings from a cabinet with the object dropper as well but that doesn't seem to work.

Stick a wall cabinet above it. Make it the same size as the hood. Change it's height to zero and maintain the correct top elevation.

I convert  them to a cabinet door symbol. Attached plan with cabinet and door symbol. The Y origin of the new door symbol needs to match the depth of the cabinet you use. Depending on the other settings in the symbol sizing options you can change the cabinet size and the hood will change with it. All 3 of the ones shown use the same door symbol.
