Add an option to show a delivery note on invoice inside an order

It would be really helpful if delivery notes (or order notes) could be shown directly on invoices when we view or print them.

For example, our delivery team often brings back old appliances, and we leave special instructions in the notes. If those notes were visible on the printed invoice, we could simply tape that page to the appliance, saving time and reducing confusion.

Could you please add an option to include delivery notes on invoices when printing or sharing with customers?
