Reschedule

I don't see an option to reschedule from the backend. When I click reschedule on a particular meeting it sends me to the regular reschedule link in the frontend, as if the guest is trying to reschedule. Also, in that option - I can't choose a date/time that's not available in the calendar (but I know my schedule and I would like to be able to do that).

So in short - an admin option to reschedule in the backend would be very useful.
