Text to go in the release notes:
Without this feature users could reserve items and choose any library as a pick up location, but there was no mechanism to prevent users from reserving items that were available on the shelf at any given location from reserving the item at the same location, essentially creating a Fetch and Collect scenario.
This had an impact on staff workloads as they had to process reservations and check shelves for items that students could have collected from the open library shelves.
This enhancement decreases the impact on staff workload by
making it possible to prevent users from requesting items for pick up at a library where the item is currently available.
