Microphone Lock Key | Suggestion

Hello, first of all I am putting out my first suggestion. He said that a friend who was in push to talk recently was uncomfortable with the constant press and could not solve it. So I thought, and I thought of a key that the microphone lock key would make sense and that people who pressed that key could turn it on and off at any time without pressing the talk. I hope this problem will be solved by other people who have this problem .. Thanks ..
