Hi @Zach780,
It's lovely you are getting repeated guests, there are no better compliments!
What do you think of Emiel's suggestion, is it something you've tried before? I'm including the official Airbnb feedback form here, so you can share your suggestion directly with Airbnb should you want to put forward the idea of a notification for this kind of thing. 🙂
Have a lovely day,
Emilie
