Country code for a custom order tracking

Hi and thanks for this amazing and simplified plugin.

I use it for my billing_phone on checkout and works wonders.

The thing is that I have a custom order tracking, where by default normally you track your woocommerce orders by Order ID AND the email that used to checkout with. But what I have made is to track the order with Order ID AND the billing_phone number that was used at the checkout.

Now what I am trying to achieve is to make it easier for my customers to track their orders without having to type in the country code manually. And wonder if this is possible to achieve using your plugin?

Kind regards,
Mark
