Addresses

Working out of Asia the addresses usually requires 2 or 3 lines to be correct, I have added for example Billing address 2 and Billing address 3 to the account information, however when I create a new contact I have to manually fill in both lines on the contacts Mailing address, it is not automatically updated.

How can I link the Billing address of an Account to the Mailing address of a Contact.

Am I getting any response on there suggestions?
How about adding screen shot in this feed-back, must be much easier for you guys, no?

Thanks
