I have a few clients over 75 who are…app-resistant…and I am unable to add their sessions to my trainerize calendar. Since their sessions do not always fall on the same time each week/month, I cannot just block the time out in general availability, so this keeps me from being able to open up self-booking for my clients. I imagine a feature like this would also help trainers block off time in their calendars for one-off things -like doctor’s appointments for example- that cannot be included easily in availability calendars, but still make a trainer unavailble for client self-booking.
