adding link in entourage task

hello... we need to add hyperlinks into an entourage task. we have an app using xcode, which automates a script (applescript) that creates an entourage task.
 
i would just like to know how to add a hyperlink into a task. we prefer a customizable hyperlink label (e.g. a clickable "Google", rather than a clickable "http://www.google.com"). if the label cannot be customized, can we add at least a clickable "http://URL" that when clicked will open up a browser window?
 
is this possible? how?
 
thanks :)
