can we get an universal mute button?

Why can’t I mute the mics of the players in a lobby before the game starts, and if I mute them in Game as soon as the game ends they are unmuted, If I am not communicating with them what makes you (343i) think I want to hear them before or after a game? All i ask for is a mute setting, that’s all. That would fix my biggest problem with the game.
