Modifying element or group from parent group

Hi there,
I often have nested groups where I want to take one sub-group and copy/move/delete it, or add it to another parent group.

I know it’s been discussed as a scripting option; but is there potential for a native Rhino command which enables the user to enter a mode where they can select/copy/move/swap/delete elements or groups contained within another group?

Cheers,
Jeremy
