Signature and blurb required for packing slip

Signature and blurb required for packing slip

Hi

We need to use the packages/packing slips through Inventory since we send out partial orders from the Sales Order. For example we get an order for 20 packages and send them out in groups of 5, 5 and 10 as per the buyers request.

What is missing is the option to add an Authorized Signature line in Inventory, Packages. But it's available in Books, Packing Slips.

Additionally, we would like to add a blurb/shipping instructions field to Packing Slips and the custom fields/Customer Notes that display in Books from Invoices to Packing Slips do not display in Inventory.
Seen here is this work-around for Delivery Method in Books.

Any suggestions?
