I'm trying to add info after the USPS and UPS shipping methods names and estimated delivery length.

Currently I have lines that look like:

United States Postal Service (Priority Mail International (6 - 10 business days))

What I want to have them say is something like this:

United States Postal Service (Priority Mail International (6 - 10 business days)) - TRACKING NUMBER INCLUDED

I just want to set it somewhere in the code to add info about including/not including a tracking number on the different shipping methods when the customers see them on the shipping_estimator box (shopping cart page) and the shipping method selection page (Step 1 of 3 - Delivery Information).

Any help would be appreciated, thanks.
