Invoice Number, Date, And Report

Hello

Cs-cart is making the invoice number when you complete the order, but it makes it with the date the order is created, not the date it is shipped/completed. Is that possible? I also need a sales report on the date the sales are completed, not when they are created. is this possible to get out of the system, or do I have to use an add on like Invoice Ocean, or somone else?

Thank you

It is not possible out of the box. It is required to use hooks in the fn_change_order_status function (app/functions/fn.cart.php) to add this feature
