Could Clipping Planes have option to clip soft shadows or not?

Could Clipping Planes have an option to select if soft shadows should be clipped or not?
Sometimes you would like to present your 3D-model as if it actually was cut in half/quad.
Currently there is no obvious way to create that directly in Rhino, without V-Ray or PSD.
I have attached an example of what I see and an example of what I would like to get :slight_smile:
