I don't always type my invoices in order and they come from a pre-numbered invoice book. It would be really helpful to have the ability to over-ride the auto-numbering system and just type in the invoice number myself. I use the reference number box for the purchase order number so can't use that.

You can use the Sales > quick entry functionality if you use a different system to issue your invoices; you can add the reference manually in Quick entries. But you cannot print them.
