Crown Molding on Cabinetry

Currently, you can only add crown molding to cabinetry using the wall editor and extruded structures.. but it would be better to be able to add crown molding directly onto cabinetry as a separate option from the wall editor. This would allow for different colors/finishes between the cabinetry crown and the crown molding of the space, but would also allow you to have crown on the cabinetry, even if the space does not have crown!
