Order number and invoice number

-- url of the page with the problem -- : www.scramble.nl

I have created an order ID in this format: {id size="5"}/{date format="d/m/y"}
This works great.
But is there a way to have the invoice number exactly the same as the order number? The invoice number is only created when the order goes to confirmed. With an electronic payment, this would be immediate. But we also allow bank transfers so then the status of the order will be changed later and another date will be created as invoice number.
