Schedulling - Need "Appointment Full" to show

I recently started using the schedulling feature on Squarespace. We are offering free classes/session, with 10 spots avialable per session time slot.  Is there any way to display "Session Full" or simply "Full" when a time block/class/session 10 spots have been filled?

Thank you. Here is the URL if that is helpful.
