Add Duo-massage option - meaning 2 staff + 2 customers + 2 bed (duo)room#4937

is there a way to give customers the option to book a duo massage. this is a service (timeslot) which has 2 employees and one room, 2 customers (although booking on 1 customer name would be fine too)

it can be one timeslot spanning 2 employees (staff members) or 2 timeslots
but one (special) room the duo room which allows for 2 customers and 2 stafff memers because it contains 2 beds, unlike other massage rooms which have one bed per room

to be clear, the wanted option is a duo massage, which means
duo room (a room with 2 beds)
2 customers
2 employees (therepists)
bookable in one easy flow for the customer
