Here is what I am looking for. I am planning to use Self Service for macOS updates on our teacher computers so that they can run the available update when they have down time and are not in the middle of class. That said, we want to make sure that the update does not go over looked so I would also like to be able to give them polite prompts or notifications that the update needs to be run but also let them postpone that update. The postpone update feature would only be allowed 2 or 3 times. After that the update will run automatically. Is this something that is possible?
