Generative Fill Respect Selection Checkbox

Currently when you make a selection and do generative fill it does not respect your selection, what it does is it generates from within the selection and blends in outside of the selection.

It would be nice to have a checkbox or a way to configure generative fill so that it respects your selection. It would generate  and blend inside your selection instead of blending outside of your selection.

I understand why it blends outside of your selection currently because it makes it easier for people to make quick selections and makes it more beginner friendly, but it would be nice to have a strict option so that professionals can apply it exactly where they want it. After all photoshop is still a tool to be used by professionals correct?
