On the pre match screen before the dressing room or in an email the day before the match have the kitman send you an email asking you if you have a preference for which kit to play in. This can be delegated but allows for players to choose which kit to play in rather than only using the second and third kits in a clash. Real clubs do this as well e.g. Everton debuted their new third kit vs Aston Villa despite no kit clash. It's a small little thing and it would be nice to see my team play in the away or third colours once in a while since Bodo/Glimt has a single kit clash in the Norwegian top flight with Lillestrom. Creating an option to design a new away and third before the start of each season would also be a nice addition.
