Improve Corner Chamfers to Remove Material Added by Rounds

Would be nice if they would improve corner chamfers so they would remove material added by rounds.

The 2 images below are both trying to create the same geometry. The only difference is the order of the chamfer.

First image has the chamfer before the round and the second has the chamfer applied after the round which does not work (should be 6mm per edge)

Corner chamfer stops at the edge of the round, will not remove round material.

Would also be nice to be able to select multiple corners to apply the same size corner chamfer to.
