Track specific links in e-mail

Hi there, 

My company just started sending out a monthly newsletter, and I was wondering if there was a function that allows you to not just track all clicks in the e-mail, but specific clicks on specific links. Within the newsletter, different links have different values, and we'd like to able to track the higher value links a littler closer. Is there a way to specify?

For example, if we announce a new white paper and include a link to the download page, is there a way to track that so we can measure visits:download ratio? 

Thanks!
