Shift + drag to move a rem but leave a portal behind

Cmd/Ctrl + Shift + M on a rem A opens a move rem dialog which allows you to search for a rem B to move rem A under.

This request is for a mouse version of this keyboard feature which doesn’t incur the search time – useful when you have the target rem open in another pane or nearby in the same document.

To move a rem you drag it using your mouse. Holding down shift while dragging should leave a portal to it behind. :)
