Hi Brian, there is a way for Rhino 7. I think they usually support clipboard format one version back so it may still work with Rhino v8.

The way it works is there is a utility program that needs to be called when you do a Paste, so you need to edit the Ctrl+V keyboard shortcut to call the utility program first before doing the paste.
