I know you can print mailing labels from the customer screen, but only for the "primary" address. This is not helpful if the customer has a separate mailing/billing address. This should over ride the the primary address if it exists, and you should also be able to print a label for any of the listed addresses if a customer has multiple addresses.

Also, there should be an option to print a mailing label from the invoice screen, as well as to bulk print mailing labels from the invoices screen when you're bulk printing the invoices.

We do batch invoicing twice a month, and they all send out in the mail. Invoicing is easy enough, but printing the labels is a real pain in the butt.
