Skip Step in MarketPress Checkout


I am using Appointments + in conjunction with MarketPress to handle the checkout process of booking an appointment. A user selects an appointment day and time and confirms this on the calendar booking page. They then go through the checkout process but there seem to be too many steps. They first have to confirm their appointment in MarketPress, the go to another page to enter their credit card info, then go to another page to confirm their credit card info, .....then they finally reach a confirmation page. Is there any way to skip a step here while sending all of the correct data through? I don't see why the user needs to confirm their credit card info after it's submitted. Once they submit it, can they just be directed to the final confirmation page?
