It would be good to have a setting in OMBI to expire and remove incomplete requests after a certain number of days..
Example: (set expiration to 90 days)
User requests movie called "Comedy Foo"
Request is approved
Request sent to Radarr/Sonarr/Whatever
90 days goes by and Radarr/Sonarr/Whatever has not found this title anywhere
An OMBI chron job runs and see's that "Comdey Foo" is 90 days old and the status is still "Requested/Approved"
OMBI tells Radarr/Sonarr/Whatever to remove the item from the request queue
OMBI notifies requesting user the media was unable to be located and has been removed
OMBI deletes (or inactivates or whatever) the request.
I would expect a user could "Re-Request" the item at that point.
