How do your supervisors see all their teams training in one place?

I get a lot of complaints from supervisors regarding our platform because they can’t find a single location to view all the trainings their team is enrolled in. We are a Financial Institution; our Branch Managers often supervise 4-9 people and need to keep track of their trainings for coverage issues. I have set up reports and shown them how to run on-demand, but they don’t love this option! How are you doing this for your teams? Any suggestions? Bonus points if your answer is in calendar form and you send me screenshots!
