You can create your own category grouping. I normally do that for each new client starting with: "Anonymizers, Anonymizing Utilities, Browser Exploits, Extreme, Hacking/Computer Crime, Malicious Downloads, Malicious Sites, Remote Access, Spam URLs, Spyware/Adware & Web Ads." WIth that grouping, I then also select: "Criminal Activities, Games_Gambles & Nudity" on the 'URL Filtering' Tab.
