Sign-up flow - select payment method on details page

The sign up Flow is Great but would Highly recommend to add a option where the client can select his payment method on the same page he can fill in his details in the custom fields for example if the client does select EFT the client does not have to provide his banking details or Proof Of Banking document but if the client does select Debit order then the Debit order page does open for Netcash and still be able to customize if the client does need to pay on check out or not. This will be a simple change with a use upside for clients who are scared to add their banking details online .
