Packing list automatic

I would like to know how I can automate packing lists, so that the dispatch schedule can also serve as the starting point for the same. We have several variations of products, sizes, etc. The same quantity does not always fit in a certain box, so it varies depending on the reference and size. We also have 3 types of packaging.

I have been looking at several things from Epicor but so far nothing works for me.

I know of Packing Slips not Packing Lists. Are you referring to the automatic printing of the slip on specific dates or the adding of fields to track the info better? Hard for me to understand the question.
