I do not think there is a way to manually choose which packing slip to be printed?
I would like to print a different packaging slip when it's a replacement order, and yet a different packing slip when I am including a return tag with the correct item. In my orders program I get a drop down list of all templates I created in my print options but I do not process my replacement orders thru that program.
Ut would even be great if I could set a rule of if the text "R" or "RC" or something is in the order # field then apply xyz packing slip and I could add the necessary words or text to the order #.
