ckeditor plugin

Hi, I need a new plugin or a modification of the link plugin for CKEditor. What is needed in the dialog box is. Two input boxes Link URL: Link Title: GA Code: The user enters the URL and GA Code for example: Link URL: "[login to view URL]" Link Title: "test" GA Code: "banners/skyscrapper" The user clicks OK In the editor if you viewed the source the link would look like: <a href="[login to view URL]" onclick="javascript: pageTracker._trackPageview ('banners/skyscrapper');"/>test</a> Ideally this would be a modification of the existing link plugin, it would also have the regex's to pickup the link if you tried to edit an existing link. A link would also need to be placed on any images, again this is why the existing link plugin would be a better route as it has this functionality built in already. If you need anymore information please let me know.
