I’m looking for this too. Ultimately, I expected there to be a “group page” that would modify the <h1> on the page based upon the group name, and add the shortcode [PM_Group id=”x”] beneath it. (where “x” is the specific group itself, of course). This page is where you’d be taken, when you click on the group name from the page for all groups [PM_Groups].
This, i would say is the minimum expected behavior. Being able to customize each page would be fantastic; but less necessary, and probably a lot more work.
