Tracking more tracking page as url in emails

Hi there, so after many tries i finally managed to get tracking more working for me. The problem i have now is that some couriers run into a problem.

Does your tracking page tracks from tracking more page when selected ? Or does it still uses cainiao ?

If so is it possible to change the url shortcode for tracking more page. So when a customer gets an email and they click “track” they will be directed to a tracking more tracking page instead, with the tracking number already included and displaying the information ?

And also is it possible to hide keywoards like, China on on your tracking page ? I know its possible on tracking more, but maybe through CSS its possible.

Please let me know.
