Request to see student course progress from assign page

My homeschooled student works on courses independently and when I assign them through Khan Academy. While I'm in the Assign part of the parent dashboard, I'd like there to be a label that says if my student has completed a particular exercise or video regardless of whether I've assigned it. Currently in the Assign area, I can see a bubble on an exercise or video that indicated that I've assigned it in the past. But sometimes she moves ahead (and we skip around in the course sometimes without me assigning particular things) so I'd like to be able to see that my student has done something so that I don't assign something that she's already done (it's hard to remember each and every exercise and video and article!). I hope this makes sense - thanks!
