Automatic Accept button after a game is cancelled

I was recently on a 20 minute queue punishment and after I waited it out and accepted a game I had to afk for 1 minute, when I returned the game had been cancelled because someone dodged and wasn't there to accept another match. I had to wait out the 20 minutes again, so what if you could enable an automatic accepting button for when people have to leave briefly in champ select and someone dodges. But it is not available for ranked games or draft pick since it's essential for you to be present for those two.
