Bind writers to publishers for notification

We have a customer that wants to connect certain writers to certain publishers. I have read in the documentation that this is currently not implemented but will it be in the future 4.5?

Example:

When writer (no admin on no page) chooses "Notify Completed Pages" the system will send a mail to the writers publisher (but not all users with admin right on that page).
