Didn't quite understand what you wanted there. Do you mean something like this?
Basically just press Ctrl+R to add additional Edge Loops on your objects to outline your area to be beveled. Ctrl+B to bevel the corner as usual.
Add your Subdivision modifier (make sure "Use Creases" is checked). After that, you can adjust the sharpness of your geometry that's affected by the subdivision by selecting the edges you want then pressing Shift+E to add Creases (the pink edges in my screenshot).
