Well, now that you mention it, Sheri...
Yes, as below, I believe our User Project Count package will do the trick, and invite you to deploy it to your environment to then get a Dashboard that shows the number of Projects per User in grid mode, and the number of Assignments per User in Chart mode, without having to export to Excel:
Once you've deployed it, since is a native Workfront report, you can then easily add a prompt for Team (or anything else of interest).
Good luck with it: I'm interested to hear how you make out!
Regards,
Doug
