I am searching for a opportunity to select the source where Instant Replay should record. Why?

If IR records the Master Output, then all overlays or (at the specific time) active slitscreens are within. But I don't wanna have all these on IR.
All camera sources are handled, switched an so on by Blackmagic hardware, and I think it would be nice and better to record the vmix input where the Blackmagic Master signal is coming in.

Example: Car Racing event, race action coming from BMD switcher to input 1 of vmix. input 2 is a cam for short interviews. If I have a interview, I switch in vmix to a split screen config with race action and the interview. But at this very moment something happens on the track, maybe a spectacular overtaking maneuver. I want that as a replay clip, but because I just had the split screen active, I also get the split screen in replay and NOT the fullscreen overtake.

what I should say: I have vmix 4k with only 1 IR. Does the Pro version have better options for setting the replay channels? But regardless of that, it would be nice if you could select more than just the output channels for IR in 4k.

What dou YOU think about that?
