Can you alter packing slip information using liquid code?

[kevin17]

Hello all

I just wondered if anyone knew if it was possible to copy the liquid code from the new order staff notification and place it into the picking order we print off when an order is placed. We want to use the picking note as an invoice to send out with the goods. but the information on picking note is not enough. 

I tried copying the code over but couldn't quite figure out what sections to remove as there were lines about emails which I do not want?

Or is it possible to edit the order form that can be printed? At the minute it shows all previous orders placed and irrelevant info that isn't needed? Any suggestions welcome.

Or prices to sort the coding?

Thanks Kevin
