Normal Blind Pick Suggestion

Hello Riot, I have a bit of an idea, it might go unnoticed but its worth a try. So i normal games the biggest problem, and many people may agree, is the toxicity, but i try not to blame the players. The most frequent cause to AFk's and trollers is when people don't get the position they called, it turns into constant arguing throughout the game and many losses. So my idea is for you to create a series of buttons that, when clicked on, correlate with the position you want. For instance i jump into a match and i am first into the lobby, therefor i clock a button that says "Top" and that gives me the privilege to lock in that position without someone arguing with me and saying they got top. Now i know this won't stop someone from trolling you and insta-locking a top champ, but it could cut back on many arguments and reports. Please vote and tell me if this is a bad idea!
