Filter Reports by Version (or not show other versions)

When working with different versions of reporting 5 (dev and prod in different versions), it would be nice if there was an option to filter reports by version. Or if its easier maybe completely hide (or gray out) reports that are not current version. In the attached image I have a number of reports, and unless I named them with a version in the report name (v.5.12 in my case) I don't know in which version of Reporting 5 my reports were created.
