I would like to record 5 devices, and from that 5 devices, choose between "Record like separate .mp3 file" or "Record tracks in the same video" for each one

Hii, I was thinking about the idea for add it to Bandicam, an multi audio recording option, for add more devices, like other microphones, and make another tracks more with them, could this be added?

I found a Bug that always happen, is when I'm using Minecraft 1.8.9.
When I close bandicam while I have Minecraft running, Minecraft stops and crash
