Can you not stick a flip on the shot *BEFORE* you start editing the
multicam group clip..?
Go to the camera angle within the multicam clip, drag on an flip effect
and it will be correct on that angle throughout the clip and hence
throughout the edit.
Do this all the time with lazy gopro shots.
Cheers,
Marcus
