Airbnb Integration

Hi Stephan,
I am not sure if I got your answer right, but I have the same situation as the first questioner, therefore again my situation and questions about possible Nuki solution:
I like to use Nuki for my Airbnb rented house with 4 Apartments being controlled by Nuki an one main door of the house. That means there is a individual key pad kombo at each apartment and one from all guests shared key pad combo at the main front door of the house. The optimum would be ehen my guest get one automatically generated code by Nuki that works with the individual Apartment door AND the main door of the house. Is this possible? If not would it at least possible that the guest gets two individual codes, ine for the apartment and one for the main front door of the house? That means one smart lock and key pad is shared by different airbnb apartments and another one is individual for the apartment.
Do I need for each smart lock an own bridge or can the bridge been shared by more smart locks if close enough? Even if from different airbnb apartments?
Thanks for support.
Best regards
Stefan
