Steve! The functionality is already there.

You can already use the Edit Glossary Includes Command to reshuffle the includes of the Hotkey Glossary. Indeed, you can use the command for any glossary.

I am just looking for a good use case.

Karen gave me a new idea with here use of the snippets.
I define a hotkey that uses a snippet and use her technique to change the flavor of the snippet and hence my hotkey. I will try to give an example shortly.
