Show Empty CAS Categories

I'm working on creating some gender converted items. I figured out that I can just edit the flags for accessories and such. My problem is, a few things aren't showing up in CAS because their categories don't have anything else in them. For example, I made a copy of a pair of basegame tights and changed the gender flags to male. But when I go into CAS, there is no tights category, so I can only see them in the broad accessories category. A bigger problem comes when I try to enable facial hair for female sims, because that category is completely absent.

Is there a way to make these unused categories visible so I can actually test out my items?
