Default email address for Need Help

How is the email address that Need Help emails are sent to determined?  Can it be set to a local resource rather than bpm'online?  As we release processes to our users, I would want Need Help emails to go to our System Administrators, or have it spawn a custom request process, rather than going to bpm'online, so that our System Administrators review any help requests before they are escalated to bpm'online support.
