Need help for custom patch

My friend is going to make modded lobbies for ps3 , but in ps3 you cant change the mod , is there a way to when the match starts the host selects what mod is going to be? like CL or zombie mod , roll the dice and others? i know this is not the ps3 section but the best coders for mw2 are here.

Uhmmmm I'm pretty sure u cant make mods for ps3 because of the design but u can for xbox.
