PES 2012 crowd supporters colors

Hello, I want all the supporters in the stadium to wear only the home team's colors. I noticed that when picture.quality = 2 supporters wear both home and away team's kits. The most wear home team's kit but there are away supporters too at the right stand (in most stadiums) or at the left stand. Does anyone know how to have only home team's fans? I know its a very old game but I hope someone to answer. Thanks.
