It would be nice to be able to add a saved group to the "Application Grouping" list, so that any executables in that group in the list will always be grouped together (not just ones with the same .exe).

For example, I have 3 email programs - 2 for work, 1 for home, (Outlook, Thunderbird, Mailspring) and I always like them grouped together.  It would be great if whenever I launch more than one of them, it would auto-group with the others that are already running.

Even though I have a saved group with those 3 programs, due to differences in their loading speeds, one of them usually doesn't group with the other 2, and sometimes I just load them separately without clicking on the saved group, then manually group them anyway.
