Make the class / appoinment calendr available for all teachers to view

I have 3 teachers who all run private lessons, booking these lessons becomes tricky and all of the teachers have to come to me first to check if the hall is available, it would be so could if they had access to a calendar, showing all classes and appointments at the studio, that way they could view availability for themselves. It would be great if they could also move their privates rather than having to cancel and re book, Id basically like my teachers to have the same access as I do to the calendar section of DSP.
