Granularity for Top Application Categories

When using the XMS-C dashboard, I would like to be able to go to the Applications tab, then go to the “Top Application Category” widget then pick one of the listed categories and then click on one of the entries listed under that category to see who is using it. Specifically, I would like to click on “Proxy” then click on “Ultrasurf” (application under Proxy category) then see who has used Ultrasurf recently. Ultrasurf is obviously being monitored, so whoever is using it should be able to be captured.
