Option to hide timeslots that are no longer available?

Is it possible to hide the timeslot that has already been taken and confirmed for a date?

For example:
An appointment was made for 9am EST on Tuesday using the online scheduler and I confirmed the appointment, however, the 9am time slot still appears on the calendar. The 9am spot is not clickable, so I don’t need to worry about someone scheduling another 9am appointment, however, it would be confusing and frustrating for someone who tries to schedule a meeting, sees the 9am Tuesday option displayed, but cannot click on it.

Hopefully this will be possible or at least a feature in the coming versions?

Thanks!
