Choosing starting sides in CO-OP

I'm not sure if it just me, but most of my Co-op matches have me playing as insurgents, like two out of three matches. Would having a voting system or a matchmaking option to choose which side to start with be a good idea? I would prefer to play as Security Forces, but it's a random chance to see which one you'll be on. It's not a necessary thing to have, but I like to hear thoughts on it.

Yeah, I love that we can now play as insurgents in coop. I hate that it changes every map without giving me a clear indication, and if I'm playing several matches in a row I'll forget who I'm supposed to be shooting 😃
