What do you think about the idea of a costume category?

Before getting Seasons, I used the hot and cold weather categories to set my sims' costumes and things like their work clothes for gardening. I really miss those ten extra slots.

Especially for Geek Con it would be extremely useful if we could set a costume for each sim or tick a "this sim won't cosplay" box. I'm aware that I can pause the game and use MCDresser to instantly change every sim in the world in costumes I set for them in advance, but it is a bit tedious.
