Its been a while since I tried to add this functionality back into Gnome, as previous versions had this option, but I believe this should still work in Zorin 17 (albeit, again, haven't tried in a bit since every time an update came, something broke and I had to fix it, so I just gave up)
Even though that's not ideally what you're looking for, it used to work. I might take a look later when I have time and try to write something up that can basically do the functionality you're looking for, ideally.
