Failure Notifications and Successful Notifications to have different email addresses as the Successful would go to the Customer Service to process, Failures to go to Inventory/Admins to fix up before Approval for Pick or Pack

Can be an extension to CC-I-28 as well so we can add multiple email addresses as well.
i.e. Sales Order Notification - Success and Sales Order Notification Failure/Error
This can be a drop down in the filter area to choose either Success or Failure for each Email type.
