One email address for all family members

We've had requests for family accounts to be more simple so we can use the same email address for all family members. Currently, each family member has to have their own email addresses, which is impractical for families with children. Can you please set up Family accounts so that there is one "managing family member" (usually just one parent) whose email address is the main email for the entire family account (and therefore the same for all family members? Of course, it's nice to have the option of each family member having their own email address for families with older kids trying to be more independent. But it would be great to create that option of one family member as the "managing member" so that all email notifications go to that email vs. individual email addresses in family member's profiles.
