We would really like to be able to enable or disable this option by school instead of for the entire district at once.

Weekly Progress Emails are a district-based option, so we have this turned on for our district, but if parents at our elementary school (which doesn't use gradebooks) select to receive weekly progress emails when they see the pop up in the parent portal, they receive weird messages and blank emails and call the school to complain that it's not working right.
