allow email notifications to be assigned to specific forms

I have multiple forms on a site - and I need to be able to specify for each form which admin group will receive the email notification for that form. There is one form in particular in this case where one of our admin's absolutely needs to receive the notifications for all of the forms on the site EXCEPT for one which he absolutely should not be receiving. And I'm stuck because there is only one possibility for setting up the group that receives email notifications about forms. Please help!!!!
