I would like to create an appointment options for a team

I have a team of 3 and in the backoffice 9 people to support my clients. They can be booked for a meeting. - I would like to have the option that i can create these groups. - I would like to be able to have made an appointment towards a specific team member - I would like to have my customers the option to choose for an appointment without team member and it assigns just 1 person random to the meeting. one on one.
