Free Text Item - Sales Orders Module

Hello,
I think one of the best features in Dolibarr is the “Free Text Item”. However, I have run into an issue:

I’d like to design a very simple Packing Slip ODT template for use with the Shipment module.
I only want to show the {line_product_ref} and a short/simple version of the description. This part works fine.
However, the problem is… “Free Text Items” get appended to the full description ({line_fulldesc} or {line_desc}). So they don’t show up at all in my Packing Slip.

Currently, I only see 2 possible solutions:

  1. Maybe there is some way to isolate and show the “Free Text Items” in my Packing Slip. Maybe I can link Free Text Items to an extra field, which I can then use in my ODT template with {…options…} tag.
  2. Hide “Free Text Items” from the Sales Order module. If possible I would rather find a way to include them in the Packing Slip. However, if its not possible, then maybe I can hide them altogether? I don’t want to hide them in all menus ( MAIN_DISABLE_FREE_LINES). Only in the Sales Order module.

Does anyone have a solution?
Thank you in advance!
