Only way is if it goes straight from the player list to the match without showing the maps and all. You can't stop it until you're in the match itself. Then you just quit.
if it shows the persons player cards when your looking for a match it means you are joining a session in progressif your looking for a match and all it says is incoming, then you are starting a new match
I'll just do it for youhttp://www.youtube.com/watch?v=MFB5SlKAqIE
