Matching viewport manipulation: Rhino & GH (+ maintaining context menu)

Is it possible to match Rhino & Grasshopper viewport navigation while maintaining context menu in Rhino?

Currently, you can match Rhino and Grasshopper viewport manipulation by Preferences>Mouse>Right mouse button and un-checking “enable context menu”.
Doing this allows for panning & zooming to be the same in Rhino & Grasshopper,
but I also lose the context menu in Rhino.

I can’t see a way to enable the context menu when I switch to right mouse button view manipulation.
The preferences under middle mouse button include: Popup menu, Popup Toolbar, Run this Macro, Manipulate view…
but no “enable context menu”

Is there another way to bring back the context menu?
