Cancellations & holding card details

instead of charging a price for an appointment and have the customer pay at the time of booking, we are looking to hold card details at the time of booking and then only charge the customer if they dont show up to their appointment or cancel within 24 hours. so the appointment would be free for all customers to book and a charge is only taken for no shows and late cancellations. this feature would be amazing and we would be willing to pay a small bit more for it if it was integrated.
