Add Design Name in Packing Slip

There is no way to add design name in the packing slip. If I have several designs in a store and allow customers to pick the design they want, there is no way to print that design info on the packing slip. When I print out packing slips for my warehouse to pack, we have to manually write the design for each order. This means, if we have several hundred items, we'll have to write that out several hundred times. It's painful. I called DecoNetwork multiple times, and they said there is custom code for that. I tried the code several different ways without success. The last call at least got me closer to the answer, but it still doesn't work.

"It has to be accessed within a specific scope, for loop iterating over items, then iterating over areas, then over processes, then over elements."

I am sure I am not the only one who needs this. If you have more than one design in a store, wouldn't you need that info?
