It would be helpful if there were a mechanism in Koha that would protect items with specified statuses from being checked in without further interaction.  For example, if an item has an incomplete return on it, if someone checks the item in, should Koha get a confirmation that all items have been returned, or that the missing part has been replaced, or that the item was paid for, or the item is being marked for withdrawal?  

Perhaps a mechanism could be in place for check in, so we can specify what statuses to watch for, and what options/reasons staff have to choose from in response before confirming check in.
