How to set up a group ringtone on Galaxy S9+

I just picked up a new Galaxy S9+ and I am getting all of my information transferred from my old S6+. I am trying to assign a ringtone to my contact groups but I don’t see a way to do the assignment. Please don’t tell me I have to go through my 500+ contact and assign a ringtone to each one. If that’s the case the phone may get packed up and returned. This has been a standard option for years.

Thanks you so much!
