Allow PO-Line type to be edited
When we migrated, a lot of our print serials were migrated with the POL type "Electronic Journal - Subscription" and a dummy order was created for the print journal subscription. We still can't figure out why/how this happened. But if there was a way to change the POL type after the creation of the POL, that would probably go a long way to resolving this issue. Currently, there's no way to go into the order and change it from electronic to print. And yet, the two orders that were created are using the same bib record. OR be able to merge two POLs and/or transfer holdings to another POL. There could be several ways to fix this issue I think.
