Instead of typing each URL to be included in a custom category, you can import a list
               of URLs through the Web console using a text file. A custom category list can be any
               ASCII text file containing the header:
            [customcategory]
            There is no limit to the number of URLs you can include in an approved list. Delimit
               separate Web addresses, URLs, and/or strings using a line break. Approved-lists support
               the following * and ? 
wildcards.
Sample file:
            [customcategory]
            www.good-job-habits.com/*
            www.business-productivity.com/*
