Reporting on Review Deadlines vs. Review Completion Dates

How have other Code Collaborator users done reporting on whether a review was completed by the deadline specified? I'm interested in being able to produce metrics on whether folks are getting to reviews in a timely manner or not.



I can use the premade reports and specify date ranges for Review Completion and Review Deadline but I am unable to find a way to have the system produce a report for me showing which reviews were "late" with "late" being defined as the Review Completion Date > Review Deadline Date.



I can always dump everything to a CSV and analyze it in Excel but was hoping that someone has solved this issue.
