Roll selection

Hey guys!

I just got an idea, since I play a lot of positions in league (any except top), I have a hard time chooseing a roll before entering queue. Every once in a while, when I choose fill I get top which just ruins a game for me and my team because I'm quite bad at it. I would be nice, in adition tu FILL that you can choose a roll in witch you wouldn't perfer to be placed in. Thoughts? :)
