Be able to book a Private or Semi-Private training session that doesn't reveal the identity of the clients to others.

For example, I have a couple who trains on a consistent schedule as a duo. I schedule them and see them as one Private personal training session. It is not a class in which others can join. It would be nice to be able to schedule them in a way that both of their profiles show their schedule and their name and anonymity are protected in the same way as my other Personal Training Clients
