Here's a cool idea, give us the option to start the game with /mute all enabled

Like many people who prefer to keep their sanity, I usually /mute all at the start of a game. Now the problem is, sometimes I will forget, and some snarky comment from a teammate will get to me and start my rarely encountered tilt. So I'm suggesting we get a checkbox that when enabled, executes /mute all at the start of each game, and the player maintains the ability to unmute. Seems like a good QOL change to the client, not to mention that I'll secretly enable it whenever I'm introducing a friend of mine to League.
