Please add Manual Microphone off/on

The microphone is unusable for me, because it keeps auto-turning off every time I pause at the end of a sentence or stop to think for a second about what I want to say.  Please add the option for users to manually turn the microphone on and off, rather than keep being cut-off.  (Note: when “push to talk” is enabled in settings it still cuts off, even when I’m holding down my keys!!).
