Is there a way to put parameters around client rescheduling/canceling?

Hi there - I’d like to be able to put some parameters around cancelling or rescheduling a booked call from the client’s end. I require 48 hours notice if they want to book a call with me and 48 hours notice if they want to cancel or reschedule, but there’s no way to put parameters in for the reschedule/cancel option. I have my 48 hours notice in all of the documentation, but it would be much more helpful to be able to do this from the back end.
