If you put the sites into a text file you can import them from the GUI.
Under Policy > Lists, Click Import. Then MWG will walk you through the import.
This will create a list for you to use. To put it to use, you need to create a rule which uses that list.
Attached is a short clip of me importing a list from a file and putting the list to use. Sorry if its very fast, was trying to keep the file size down.
The list I imported had only a few entries, with varying formats:
http://google.com digg.com lifehacker.com/test downloads.mcafee.com
In the rule I used, it uses the "URL.SmartMatch" property which basically accepts any variation of URL entries (except wildcards). For more information on the URL related properties, see: Web Gateway: Understanding URL related Properties
