Hair Color Change in CAS

It seems to be impossible to have a different hair color per outfit. Say you pick the color “pink” for the hairstyle you choose for the first outfit; you go on to make a second outfit but you want the chosen hairstyle to be “red”. Then the red automatically applies to all the outfit categories, the first one included. Why does it only want me to have the same color for all the outfits? 🫩
