Track Specific Link Statistics


I am setting up a sponsors page on a website. What I would like to do is have each specific sponsor’s link trackable for the associated client. So for example, if Bob from “Bob’s Pizza” wants to put an ad on my website, is there a way I can have him log into my Piwik with a guest account that only shows him click statistics for his spacific ad? Or, if more realistic, can an email report be set-up to send Bob the same statistics? If you know of any other software that does this, it would be extremely helpful.
