I have 2 very different models with cosmetics that I like using, and its a pain every time I want to swap them. I gotta pick the right model, then swap each individual cosmetic item to the right thing. While not a terrible pain, its something that could be (presumably) easily fixed.
Add a number of “Loadout” slots that you can name. You set what Model it uses and what Cosmetics it uses, and save it. Then, whenever you wanna use that set, just click the button and everything changes! It would be very nice quality of life, especially for people who like to RP as different characters, or maybe a small group trying to make a video with tons of characters and need to swap outfits quickly.
