Order of Operations Client Checkout

When a client is placing an order, they will first select a service from the order page and then they are taken to the checkout flow. There are multiple stages in this flow, and I would love the ability to re-order these stages. Example: Currently this is the order:

Listing Details > Appointment Details > Additional Services > Contact Info > Questions > Order Confirmation

I would love to be able to change the order.

Thanks!
