The University of Washington is requesting this for cancelling multiple requests at once. Right now, if more than one request is selected, and then the Cancel button is used, Aeon sends an individual Cancellation email for each request. This is helpful if the requests are for different patrons, but they feel that most of the time, they would be cancelling in bulk for the same patron. There is also not "edit email" option when using the Cancel button to cancel multiple requests.

In response to Genie's questions... I like the idea of an itemized list of what is on hold, although perhaps the list wouldn't have to include all citation fields for each item. One scenario we discussed was that once paging for a user is done, the person putting the material(s) on hold would manually send an email, selected from a list of templates, to let the user know the status of their request(s).

I'd like to plus-12 this!

This is exactly what we want!! Except being able to send those batched emails to staff in order to fulfill the requests.

This could maybe be rolled into a solution for this topic - https://uservoice.atlas-sys.com/forums/568075-aeon-ideas/suggestions/17695762-single-invoice-containing-multiple-transactions?tracking_code=67c9a26979021226111aaa21354f6397

This is particularly important to look at for sending out notifications for multiple related transactions immediately, as well. In cases where we want to send a confirmation of a Scheduled Date or a Cancellation email, it's more common than not that a separate email is required for each transaction. We should be able to easily group all the relevant transaction details together in one email.

It's a major inconvenience to our users to get multiple emails, and a major inconvenience to our staff to have to manually craft emails for covering multiple transactions. This kind of functionality is very much expected from both ends of the service for software like this.

There are several things to sort out about this.
When would the email be sent? On a delay? At the end of the day? Manually?
What would the template look like for an email pertaining to 2 or more items? Is it always an itemized list? Does it just say you have 10 things on hold?
