Wix Bookings Appointment For Multiple Participants

Is there a way for clients to book an appointment with multiple participants? Our services include private and semi-private swimming lessons. We want a booking process where clients can book appointments and have to enter a field on how many participants/kids they want to enroll. Class/course is not a good option for this since this is a private swimming lesson and focuses on teaching swimming lessons exclusively, we don’t teach 2 families on the same schedule.

To sum up, what I want is an appointment service where clients will enter the number of participants they have.
