Help center Sign up notification - How to change which admins receive notifications

Our Help Center requires users to be approved before they can access it. The "Help center Sign up notification" email is going to all admins on our account. There are only one or two people that will be approving applicants, so I'm trying to change this notification to only go to certain users. Is this possible and if so, how/where is this setting?
