In our shop we extend the side panels of upper and tall cabinets 2" to accommodate for moldings.

I saw the Valence Height Top option in the Globals, but that seems to take from the overall cabinet height and we don't include those 2" in our "cabinet height". Along with that I saw the Left/Right Full Height options in the Product Prompt but I couldn't find them in the Globals.

If anyone has any idea how to activate Left/Right Full Height in a Spec group and auto-subtract 2" from elevation dimensions, or has a better method, your help will be much appreciated.
