Default Email Notification Settings for Entire account

It would be nice to be able to set default email notification settings for all new users in an account. Currently with every new user, I have to change the email notification settings manually for every individual. They all are adjusted to the same selections, I would like to have a default setting that automatically presets with the admin selections for every new user. I imagine this would fall in the Customization area under Admin, then in the user profile.
