Multiple mods

Hi, I was wondering if you can have multiple mods for say, smg's (or any other type). 'Cause when I try to use corndog's mod for all SMG's ir works but I also found a mod for the p90 that I'd like to use but can't without changing all the other SMG's back to normal. It's sorta of annoying.... So I'm hoping there is a way to have multiple mods...?

just re download ca and all ur data shld be back to normal

Well unfortunately that wasn't my question, my question was; is it possible to have multiple mods in AR, SMG, etc.?
