You have to apply an inner tooling or edge shape to cut the drawer sides to the shape you want. As usual you can save the shapes in the Structures library and apply as needed.
If you often have these drawers the best is to make a standard drawer model that you call up and edit as needed.
We like to make our own drawers and sometimes in wardrobes or pantries we have a drawer that is full height at the back with the two sides graduating either straight or with a curve to a lower front.
