I would like to know how to show the URL of a carrier to redirect the customer to carrier's tracking site, if it's possible with the tracking number in the URL.
This pal did it but for Magento 1 How to modify tracking link target
However I cannot edit the phtml template, because this module is intended to work in different stores, so if I use app/design the purpouse of using just the module will be lost.
Here there would be an extra field called URL
Thank you and regards!
