Can you & if so, how do you edit a specific goalie's kit? (ie. assign a specified kit for each goalie you want??)

I tried the Juventus GK kit and other goalies in the game are assigned to that kit.

The only way to really have the keeper uniform only for that team is by using FifaFX http://www.fifafx.de
or the Spanish FifaFX http://www.spain.fifanet.com/fifafx :D
