Mix Minus in USB

Been using the Flow8 for hybrid events, where we use the Flow for FOH as well as for streaming, but sometimes we have a Zoom call as well where we have speakers and want to send the audio from the room, but the USB gets loop backed into the streaming creating repetitive audio. Maybe a special setting where you don’t send back the USB audio back to the streaming.

Please and thanks.

Also, when can we expect a new firmware update
