Would it be possible to:

1) Disable the phone number field in the saved address section for logged in customers, and/or include it as an account field, the same way email, full name, or extraclientfield1 is? This is so the phone number is associated with the account, not the address.

2) For logged in customers, allow for an extra field (like extraorderfield1) to be associated with the specific order rather than the saved address? This would be helpful for repeat customers who want to include a special note on the order (like a PO number, or another message), without having to delete it out of the saved address every time they order.
