How to book for more attendees at once?

Hey, Tecchies 🙂

I've been trying to set up my bookings page so that a single user can book an appointment for more people, but I haven't found any solution! Have I missed anything?
To recap, I just want users to be able to select that they will attend the appointment with x more people, and I want that number to be kept in consideration for the max attendees limit.

Is that possible?

Thank you in advance!
