How to show result in Rhino for selected elements?

The current Karamba3D Beamview or Shellview shows all the 1D or 2D elements’ graphical results in Rhino. But how to show graphical results for selected elements?

In case it’s not currently available, is it possible to add this feature?

You can restrict the preview by inputing an element ID or “bounding” brep in the ModelView component
