is there a way to select which uniform to ware, cus i just played Cruzeiro(Brazil)
and Cruz Azul(mexico) and they have the exact same color uniforms, and they both wore there hoem kits and it sux to play games like that , especially if its a cup game-- so is there a way around that

Go to the edit team screen, change the kit to a common one, change the colors, and then cycle thru the kits until you find the custom one and save.

If you want in every game, the teams to wear away when they are a way, and home when they are home, then select the top line of the kits for home white and the away black (asuming they have installed kits, not ingame made ones) do this for all teams u want, and you are right.
