I tried importing billing address to companies in my contact but it didn't seem to work. It executed, but it didn't add the new contact with address type invoice to the company. I used the external ID when I exported the companies and when I imported them back in with the billing address. I'm not sure if I'm missing something or what's going on.

Also, can you only import a single address in per contact? Wondering if it's possible to kill 2 birds with one stone and import shipping and billing at same time.
