USPS Carrier and tracking auto update

Hello,

Would it be possible to includes USPS as a courier option for this plugin?

Also, I have a shipping label provider (Shippo) that currently sends the tracking number and courier information to the order notes section in Woocommerce, is there a way to grab this information and load it into the plugin fields automatically? Here are the transaction object labels Shippo uses: https://goshippo.com/docs/reference#transactions

Thank you!
