Airbnb Additional Guests - Multiple Scenarios

We'd like to charge a different amount for each additional guest per night – for example, $5 per night for a 3rd guest, $10 per night for a 4th, and $15 per night for a 5th. Is there any way to set this up so it will sync with Airbnb or is only a single additional guest surcharge allowed?

This definitely won't work with Airbnb.  You can do it for direct bookings though, and I think perhaps for Vrbo, though I'm not completely sure.
