title: Change the shipping method name in backend
body: <p>I have changed many shipping methods and its display on the front end. Because of the customization, I have given names programmatically like "Standard: 1-2 business days:2" Now I want to change the display in back end and the display of the methods like the above to "Standard (1-2 business days)". I want to know where to change these names when saving into db.</p>
