In the forecast module , when a salesman changes his forecast, does the salesmanager gets a notification ?

If a salesman adds or remove line items from this forecast and then hits the commit button, the salesmanager will see by means of green up arrow or red down arrow , in which direction the salesman's forecast moves. But is there also a mail notification possible to inform/warn the sales manager of (important) changes to that forecast ?

Thanks for your input
