Please give us a way to boot people from the game in champ select

If somebody is being toxic in champ select, or has a troll pick, the team should be able to boot them and prevent us from having to play the game with them.

I started writing this post when I was in a champ select with a Master Yi support. I knew the game was going to suck and of course he ended up feeding. This situation could have been easily avoided if we could have an option to vote to remake in champ select.
