Allow library to alter default status for "Mark Unavailable" in Missing Part Checkin
This currently defaults to "Display," and displays with that status in PAC. Display is a non-circing status that is actually used for items in our special collections, so we can't rename it to something like "In Repair."
If system admin gave an option to set a default status when "Mark Unavailable" is selected from Missing Part Check In, it would streamline workflows as we wouldn't have to go back and change the status in the item record.
