Hey @olefirenko Thank you for the amazing package.

I found it necessary for me to be able to specify the short_name or long_name because I needed to further handle the country code.

But I was not able override this because it was hardcoded in the component.

With this Pull Request users will be able to override.

Let me know if you want to me to change something or feel free to adjust as needed.

All the best
Jonas
