Group Appointments

Setting up a private and appointment has been a useful tool. Would it be a good idea to also be able to create group appointments? We typically have one time classes/master classes that dancers sign up for ahead of time. We currently use signup genius to organize this, but it would be much easier for families to log in to their parent portals to access the class signup. Would be nice to have it all in one location. Being able to set a max appointment size would be helpful too.
