Groups of Services in Appointments+

Hi, I'd like to offer appointments to two different group of customers om my website.

Is grouping of services possible in Appoints+ ? I'd like to be able to offer appoints with one type of services to one group of people and another type of services to another group.

Both groups should not see services of the other group.

If so, could you tell me how to do it.

Thnx in advance!
