Address fields for Contacts and Accounts

Address fields for Contacts and Accounts

We need the same two sets of address fields (e.g., one set for Billing/Physical Address and one set for Shipping/Mailing Address) to appear on both the Contact and the Account form.
1. Not possible to map these fields from the Account form over to Contact?  It appears not.
2. Not possible to create Address-related custom fields in Account and map them Contact?  It appears not also.

Is there a solution for this?  THANKS!
