[Feature Request]: Individual rounded corners

[PWagner1]

From @MattH-Work via Discord

Is it possible to control border round on specific corners, not just on edges top-bottom-left-right
I would like to round (with a value of 5) Top-Left, Top-Right & Bottom-Left corners, but keep Bottom-Right with a rounding of 0 (or combinations of)

Looking for this

Will need to have something similar (with different word / nomenclature) to the border drawing designer control:

It will also need to apply for all controls () and all styles (again)

Which means the use of the Rounded Rect Path code will have to change ! (i.e. use it -> Modify it -> pass in current designer style overrides)
