Problem with return format of shipping labels

Hello again,

I have encountered a slight problem when retrieving shipping labels. If there is only one box, the label is fine and prints great. However, if there is more than one package, the pdf I get in return has crammed all the slips onto one page. I tried specifying multi_page for orders with more than one box but this didnt change anything. Is there any way to get a return pdf that has each label on its own page?

Thanks!
