Order & Invoice id


When I want to print and save an invoice. It uses the order id instead of the invoice id. This is not usefull if you want to store the invoices on your local HDD. It will use the order ID and not the invoice ID.

When you print the invoice in pdf it says Invoice - 1200.pdf (order_id)

I want it to use the invoice nr. Invoice - 51.pdf (invoice_id)

Any solutions for this?
