I am not 100% sure you understood my question - My apologies if I misunderstood you but I am not able to try what you suggest as I have not downloaded Big Sur - as it may not be of advantage to me.
However - there is a feature on iPads and iPhones which has not in the past been available on imac photos. It is mostly used to adjust architectural images - it allows a vertical adjustment to pull the top of the image forward - or in horizontal the left or right side of an image forward. It is available under the Edit then straighten on the iPhone.
Thank you for your time - and apologies if I misunderstand you - correct terminology is sometimes hard to think of.
It is feature I find invaluable - No I have to transfer the image to my ipone adjust it and flip it back to the computer!
