Is there any way that a "Mark Video" option can be added if you have a khan academy account?

Hi, 

Is there any way that a "Mark Video" option can be added if you have a khan academy account? I am studying for the MCAT and I would like to mark some videos so I can easily identify the ones I need to come back for re-reviewing the material. It would also be nice to have those videos come up as a different color on the main MCAT page (other than the blue circle that shows up around the play button) where I can see the list of videos that I have/have not watched yet. This feature would be a big help in enhancing the Khan academy experience!

Thanks you for this amazing platform.
