Custom email alert receipients by WAN

The existing email alerts are fine, but it would be great to have the ability to have alerts for a particular WAN go to a specific email address. For example, BOB is in charge of WAN2 and if WAN2 goes down he should be alerted. However, JOHN is in charge of WAN1 and WAN3 so he should receive email alerts for WAN1 and WAN3.

This isn’t urgent but would be a useful feature. Thanks for considering this request.
