Book multiple service providers

A website I'm working on should offer the possibility to book 2 service providers at the same time. Is that possible with Appointments+?
The website is for a massage professional, where one should be able to book a duo massage. That's a massage for two people, being administered by two service providers simultaneously.
The system should be smart enough to deal with this, disabling the availability of two service providers at the same time in case of a duo massage.
