Inactive Policies and Archiving Policy/Rule Templates

DLP Team,

Is there a way to run a report of all policies that have not had any activity ever (no matches and/or hits) or from customized time frames?

Also, I see that there is a way to export a rule/policy template individually; however, is there a way to archive (export) dormant policies within DLP itself rather than sending all of them to a shared drive (in order to save on disk usage).

I would like to create a folder within DLP of all exported rules as templates for future use instead of deleting them in case we ever decide to revive an existing policy template (to prevent having to recreate a good rule from scratch).

Any advice or potential workarounds are always welcome (I realize there isn't a feature for everything yet).

Thanks!
