Ring Selection with RMB-Doubleclick

The Topic says it all - is it possible to set up RMB to select Full and Partial Rings analogous to the LMB-Behaviour? If not, this was a great addition - I love this in Silo.

Double MMB Click is ring selection, would be hard to put it on rmb since that had a radial menu on it.

I have RMB remapped to a Camera-Control and MMB to the Menu.
So RMB+Drag is taken but RMB Click-Events are still free on my Setup
