Expand Reporting Functionality to Administrators (managing Users) Merged

Admin role here looking for some help in managing users. The recently applied filters (filter by Product/Product Line, Filter by Role) help somewhat, but aren't too powerful and in fact confusing as they don't work together (i.e. show me all users of Product 'Umbrella' where Role = Product Owner) Workaround is to export all users to CSV and manipulate outside of the system.

Suggestion:

For folks in an Admin role, is it possible to simple extend the ARE (Aha Reporting Engine) to the User area? That way I can build a dynamic report once, and use that as people come and go.  This would save me tremendous amounts of time.
