Labels & PAB (Additional Fields Possible?)

Our users are printing labels (Db based on PAB template) but need some additional data. It seems the print function (document styles) presents label options when a PAB-based Db is open and knows to pull in the basic contact information. Is there a way to add an extra field from the contact form? e.g. account #?

I found the shipping labels (listed in print dialog - document styles) in the PAB design.
