I would like to edit some existing reports in Service Desk. Many report do what I'm looking for except for one thing. All 'closed reports' report the closed/resolved step in the workflow. We have a validation step on which I would like to report. How can I edit existing reports to match this? We are currently running 6.2 but can upgrade to 6.5 if needed.

With the report builder in 6.5 is it possible to edit these reports without having to make them from scratch?
