Adding a Co-Teacher to a Classroom

Please add a feature that allows the original classroom teachers to add co-teachers to Khan Academy classrooms so the original classroom teachers don't have to share their login credentials with those other teachers. 

It is becoming more and more common for teachers to collaborate as they strive to meet the needs of their students.  While there may only be one "classroom teacher", there are often more support teachers / coaches that interact and track student performance; such as Title 1 teachers, EC teachers, gifted teachers, etc...

While researching to see if this feature was available, I came across the following response from Khan Academy:

"I’m afraid we don’t currently offer the ability to add a co-teacher to a class or share a class among multiple teachers. A class is always tied to the Teacher account that created it, and only that account is able to see scores and manage assignments for the class."

Can the ability to share a class among multiple teachers be added to Khan Academy classes?

Thank you!
