I will explain.
I have store with products which are shipped from different curriers. And when I get the tracking code I do not know what kind of currier did they use.
So if I add tracking code to the order and I select some kind of random currier after redirection as expected it shows no information in your page. (This number can’t be found at this moment)
Then in your page, you can press the blue(it can be different color) Select a carrier to track button, and press Auto-detect carrier. And then when you press Track it will show information.
So I was wondering is it possible to add this option in the dropdown menu where you can add curriers. Add this option and after redirection to your page, it will detect the currier.
