Option to change duration of booking by staff#4861

It would be great, if the staff/admin can change the duration of a specific booking. Of course the services have their standard duration time, but often you have a client you know you will need 10 more minutes as with others or there is this one client for which you always just need half the time.
It would be super helpful to avoid dead worktime or overlapping, if the staff/admin can change the duration time for a specific booking.

YES please allow duration to be editable when accepting requested appointment or anytime really!
