I installed the Integrated Checkout Without Account (COWOA) module in Zen Cart 1.3.7 and I am looking for a method to change the page flow.

Now index.php?main_page=login has the option "Checkout Without An Account"
which leads to "Step 1 of 5 - Billing Information" (index.php?main_page=no_account).

After I enter the Billing information I get "Step 2 of 5 - Delivery Information" (index.php?main_page=checkout_shipping).

Instead of using the Billing Address as Shipping Address
(with a Change Address button which leads to index.php?main_page=checkout_shipping_address),
I would like that page to have a new empty Shipping Address form.

How can I accomplish that?
