[2020] Please - we need a "mute all" keybind.

Sometimes teammates just won't shut up when they're dead. Sometimes they're just rambling an annoying. I don't want to not hear them for the rest of the game, but for the rest of the round - sometimes yes. Please, make this happen. It's unbearable to either have to listen to your dead teammates who have nothing to add for a minute or spend 5 seconds every few rounds to go into menu and click buttons :( Such an easy QoL feature to add, please please please.
