Voice Chat - Push to Talk

Can we get a Push-To-Talk function for the in-game Voice Chat? The fact that you guys added Voice Chat but only the option to Enable/Disable is beyond me...

There's definitely people who wouldn't mind or even like to use Voice Chat, but definitely not when it's Open Mic and there's tons of background noise the whole time even when not talking.

^ yeah, it's so crazy it's kinda funny... kinda...
