Can notification emails be set per Project Area?

Hi,

Is it possible to configure the notification email settings per Project Area? We have a couple of PAs, and would like the emails that are sent when Work Items are assigned to come from different email addresses.

I found several posts on how to setup email for the server such as https://jazz.net/forums/viewtopic.php?t=724 . Is it possible to override these properites in the Project Area:
com.ibm.team.workitem.notification.mail.from
com.ibm.team.workitem.notification.mail.reply

Thanks in advance!
Jeff
