Supplier - Contacts - Addresses

Hi AP Team,

I have following questions about addresses,

1. Can we add a contact and a address with out associating with a supplier site?

2. Can we associate an address to the supplier record with out creating as site?  

As per documentation that I reviewed that all addresses should be associated to a site. I did not find a way to add additional addresses with out associating a site....... Let me know if you have any suggestions or references for review.

Thanks & Regards
