Task notification email contains a link that goes to Tempo rather than Sites. Is there a way to edit the link so that it goes to Sites?

The task notification email contains a link for the user to click to take them to the task.  The problem is that the link takes them to the Tempo version of the application rather than the Sites version which confuses the users because it looks different.  Is there a way to edit the link so that it goes to the Sites version every time?
