Thanks, Leo. I ended up creating a Toolbar of buttons, one for each Tab Group, which achieved the desired result, although I do need to update this manually every time I add a tab group. The list of tab groups selectable from a dropdown menu on the toolbar doesn't require updating, but adds an extra step. Good enough. I also found another post (here) where you had explained how to do this (just in case anyone else is trying to achieve the same).
