It would be great if gather_print_notices could be run with a list of patron categories to include/exclude. I'm imagining one new flag for an allowlist and another new flag for a deny list. The use case at hand is a library that wants to mail printed Hold Available notices to some but not all patrons. HOLD notices generate as print by default, so there's no way to simply turn them off for patrons in the category that should not receive them. A new flag in the gather_print cron would allow us to at least stop emailing them to the library along with the HOLD notices they do want.
