Customizations to Billing Manager role & Billing email notifications

 Currently, the Billing Manager role ONLY has access to the billing settings (nothing else). We'd like to see a role that is similar to the Report Manager PLUS the billing settings (so this person can see the call log & reports). Maybe this can be designated as a Billing + Report Manager.

Additionally, we'd like the ability to customize who gets the billing email notifications. Right now it's ALL admins (even if they don't need or shouldn't get them). Some users may need admin access to control settings but don't need the billing notifications. So just the ability to further customize & control who has access to billing & who sees those notifications.
