Is there a way to control access to data in JRS reports at a team area level?

I have a project area with two team areas (alpha and beta). Each team area is associated with its own timeline and iterations, and I created a category called Private, so that I can segregate access to work items among members of these team areas. When I file a work item planned for an iteration that belongs to team area alpha under Private, members of team area beta won't have access to this work item.

Now here's the question: is it possible to keep this access control level in JRS reports? According to my tests, JRS will only control access to data at a project area level. So if an user isn't member of my project area, he won't be able to create a report and limit the scope to the work items in my project area. But I still need to control access to data at a team area level, because I don't want users from one team area creating reports that displays Private work items from another other team area. Otherwise they'll just be overriding the data access control policy.

Any ideas on how to get it done? By the way, I'm testing JRS in version 5.0.2 iFix005.

Thanks!
