How can I include additional notes on my packing slip?

Hey there! I recently added the features ‘add order notes’ and ‘is this a gift?’ to my site. When someone enters information here, it pops up on the internal order page as ‘additional notes.’ Unfortunately, this does not populate on the packing slips, and there is no variable reference for this (that I know of). Does anyone know how to make the note appear on the packing slip? I’ve included a sample image of the section I am talking about. Thanks!

Following, i need the same help
