dynamic que/ new champ select reporting

Riot should look into being able to report players in champion select. I just had a game as a solo player matched with what i assume was a 4 man premade. I had to leave in picks because my own team banned me out and then someone picked for mid after I already locked it, leaving us without an ad carry. Now I have to eat an lp loss and sit through the 5 minute wait to requeue because of the actions of the trolls i got matched with. This also isnt the first time this has happened to me either. Currently there is no recourse for people in my position other than to do what I did and eat the penalty, or play an unsatisfying game with a likely losing outcome, just to report the trolls. Something should be done to mitigate this, like the ability to report players without having to sit through the game.
