SRIV Adding new Clothing Categories

[[GoSP] Jon]

I have seemingly been able to add a new slot and clothing category using customization_slots.xtbl and customization_categories.xtbl as well as moved some existing items over to the new slot. I have also set up the new category to use the new clothing slot. What I have not been able to find is where the game figures out what Area corresponds to what category in the menus so it can populate the shops and the wardrobe with the clothing items that belong to the new slots and categories. Any help on this is greatly appreciated. Thanks!
