Grouping Assignments

I am looking for a way to be able to group assignments by learning target or unit of study and I hope this would be an option that wouldn't be too much work for Khan Academy to implement.  Here is what I envision:  As a teacher, if I have several activities, videos, etc. that I want to group together, I can create a group, name that group (ex. "6.EE.3 - Decimal Operations"), then add assignments, activities, videos, etc. to the group I just created.

As a student, when I go to assignments, I would see "6.EE.3 - Decimal Operations" and the due date for the GROUP of assignments.  When I click on the group, I would land on another page where I would then see the list of individual assignments within that group.

Thanks for considering this request, or if another teacher has found a work-around for this.

Cheers,

Jon
