Is your feature request related to a problem? Please describe.
When a hold is blocked via the Symphony hold map, the following message displays:

Describe the solution you'd like
This sounds like delivered language and I hope it can be customized. Users will likely see this result more often in a curbside delivery environment, where holds will be restricted by user profile and holding library (users will only be able to request items from their institution). Some consideration is needed for how specific the language should be. Better ask Peggy... oh, wait...

Also applies to NEOS discovery.

We use a Web Services Place Hold application that @jhennig built for both UAL and NEOS Discovery, so we can intercept that message and replace it with better text (without adjusting it in Symphony). We should come up with text for the current pandemic around holds being restricted to core users (whatever term we/NEOS want to use), and then have more straightforward text we can revert to whenever we go back to the regular holds process.

@redlibrarian Sounds good - I will chat with Elaine later today and consider discussion at NEOS Access on Wednesday.
