Schedule reports with filters?

Schedule reports with filters?

Is it possible to schedule a report with a filter applied? For example, my goal is to schedule a report on unlicensed mailboxes. I want check "Don't send empty reports" and only receive the report when there is a "real" user with an unlicensed mailbox. This would work if I could apply a filter to remove the Discovery Search Mailbox for the schedule report.

Thanks,
Michael
