I have enamel badges, stickers  and tote bags as gifts with each customer order.

After each invoice I go to Customer screen MEMO and note what was sent so next time they get a different gift.

It would be a lot quicker if there was a MEMO link on the top bar of Product Invoice page, so you could click the button and a drop down shows MEMO details from the Customer screen.

Could this be considered on future update?
