AF/Rack focus feature request with single auto focus

Not sure if it’s still available but Ursa broadcast used to have set A-C points for a focus pull with AF-S. The AF-S on Pyxis with L mount lenses & adapted ef lenses is great & really snappy although only in the centre…or so I thought! My Pyxis glitched & I could move the AF-S box to the middle or two corners.
This proved the box can be placed so essentially with minor firmware update you could set the box on the end focus pull position, set the focus on a subject then with the AF-S button, pull focus quite effectively!
Requesting to reinstate the A-C rack focus positions in all capable cameras starting with a touch screen moveable focus box please.
It’s a simple user interface update to get this started & tested.
