Feature Request - Ability to edit closed tickets

Our agents have requested over and over again the ability to make some edits on closed tickets.  In particular, some of the metadata fields.  Sometimes actions happen that might cause tickets to fall out of agents active tickets queue so they don't realize it is approaching 28 day autoclose window, or an organization is no longer part of our service and tickets get bulk closed before we've had a chance to change certain fields appropriately.  

It would be nice to have some ability to change things on a closed ticket

Thanks
