Add a Library or Edit Library Information>Libraries

Add an "Allow other libraries to handle digitization" tick box similar to the "Allow other libraries to handle personal delivery"

This intention would be that the item to be digitized would not need to be sent back to the library originally listed as the managing department.

This is particularly useful for those with multiple digitization departments in different locations. It would save on postage, time taken to complete the request and reduce manual intervention and monitoring by library staff.

For further clarification: Information on- Allow other libraries to handle personal delivery is documented here. Under Editing a library and it is listed in step 7, I would like similar for digization requests.
