Packing Slip Line Items Comments

On the Sales Order line comments, if you click the 'Duplicate' button, this
puts whatever comments you have entered onto the job, the customer packing
slip line, and the invoice line.

On the job operation comments, the po and subcontract shipment lines pull in
the operation comments.

Does anyone have a way to pull information off work orders, purchase
orders, or sales orders and post to comments of the Packing Slip Line
We spend a lot of time cutting and pasting, or just typing the
information that is available else where in the system.
