Links within posts stats

I am looking for a way to track the # of times a link (not to an external site) was clicked in a post. I have WordPress.com Stats and there is a section under “Clicks” that shows similar data, but it only shows data for links that point to a site outside of our own. I have added media links and want to see the # of times these links were clicked.

Is there a separate plugin for this or a way to view this information with the current stats program I am using?
