Labels to suit Australian standards

PLEASE create an option for us to select label sizes. Here in Australia we use A4 size paper (longer and narrower than the USA "letter" size) and the labels just don't work. We've resorted to importing labels from the USA that should work but still didn't line up in our printer.

A task that should take a couple of minutes takes a couple of hours to export data, reformat, create a mail merge and hope for the best!

PLEASE PLEASE PLEASE!!!!
