Scheduled Event - PO Maintenance

We would to set up a maintenance schedule that would do the following;

- delete opened emails that are older than 180 days old, moving them to the trash and not touching unread emails.
- delete trash older than 10 days old

The expire/reduce schedule does not delete unread items, but does not move deleted items to trash. The delete set in client options moves items to the trash, but it deletes unread items too. It seems neither action fully does what we want to do, but also does something that we don't want to do.

Any suggestions? Thanks in advance.
