Make it possible for one emoji to be automatically added for all of that appointment?

I’m teacher training and so my calendar is packed with lectures, classes, meetings, appointments etc. Mostly they’re separated by colour which is fantastic but I would also love to make emojis link to multiple of the same kind of appointment if possible? Like, I have two different campuses so being able to set one emoji for the first and a different for the second and then sync it across all of the upcoming ones would be incredible if that’s possible!
