Add specific email for a group

Many technicians ask us if they can receive notifications on a list of their service or area. For example, the deveoper unit has an email lilke "dev.app@xxxx.yyy".

It would be great to be able to assign a specific email to the groups (optional) and that it could be used for notifications.

That is, enter the email as one more data of information group and have the option to mark if you want to be notified via notifications in this email.
