Manny,
That option already exists in the Social -> Notifications/Analytics tab. The setting you're looking for is "Add Google Analytics Tracking for New Likes". However, that setting will simply add the tracking functions to update your Google account. You'll need to manually insert the Google tracking code with the UA-xxxxx-1 number. We don't do that because there are so many other extensions and easy manual ways to do it that it would likely cause more conflicts if we did add it on our own.
Hope that helps,
Alex
