Show an ITEM's Custom Field on an Invoice

Hi all,

Running Accountright 2024.

We use custom invoice forms to generate a 'manufacturing order' , which is then used by our storemen to select and pack items for shipment. 

When specific items are on the order, i'd like a message/reminder for the storman to appear on our manufacturing order - such as "Items should be individually wrapped". 

I already pull CUSTOMER specific information/reminders such as this into the manufacturing order custom form from the customer cardfile (using Custom Field #1), but I'd like to pull in ITEM specific information from the ITEM cardfile.   Unofrunately, I don't seem to be able to reference this field directly on an invoice document... seems to only be useful for report filtering?

Is there another way I can set up an item to print item-specific reminders to the storeman on a manufacturing order?

Thanks.
