Server Voice Channel Recording

Hi So I run a discord server and ive had many issues of members coming to me or other staff on my server saying this he did this she did that kinda of thing and due to no way of recording multiple calls at once because i have a bot thats records the call when a command is executed but it can only record  channel at a time and i need a way to record multiple channel because when they come to me or my other staff they dont have proof because they cant record that channel if becuase the bot is already in use so i would like to see a feature for voice chats so that when a channel has 2 or more people in it the channel automaticlly starts to record the call and then affter theres 1 person left in the call is puases the recording and if the last person leaves the channel i stops recording and saves the recording to a text channel that can be set by the server owner or a server admin and saves the recording and either a .wav or .mp3 file or what every that a staff can then either download to save to a folder on pc to listen to laster or can listen to the recording from the channel without needing to download it and this would be good feature to have if ur starting a new server and are having issues with people being in a voice chat and fighting and no one having proof of it so u cant punish anyone so yea this would be a good feature
