Issues with fields and taxes

I am seeing 2 possible issues:
1) I don’t see a Billing and Shipping State field in the Field Default Value drop down when creating a new field. Obviously those 2 fields are part of the default woocommerce billing and shipping fields
2) If we are displaying taxes in the view quote page. Since in our system taxes are based on the shipping address, if the user changes their shipping address in the view quote page (we added all the default billing and shipping info to the page), your system doesn’t seem to change the taxes shown based on the change to the shipping destination
