A lesson that may also be included on other courses

Hello, I would like to suggest a very simple feature to make browsing courses much easier. For example, there may be a video or a text-based lesson (usually called "reviews" I think) that may also be included in other courses. In my experience so far, many math skills in some course also exist in others (so when I do those exercises and finish them, the percentage of completion go up in other courses as well even though I never even started them).

My suggestion is simple, is it possible for a video to indicate which courses it is included in and exactly where? For example, if there is a video on say, long division in the Pre-Algebra course, it should say that apart from this course, it is also included in Mathematics 1, Grade 6th Math, etc.

What do you think? Would this be considered a useful feature?

My main point in asking this is that, I download videos and lessons and place them in my offline storage (I am kind of an e-hoarder unfortunately) while keeping their original structure. For this reason specifically, I don't want to download the same video multiple times but instead make a shortcut to the first one I downloaded in other courses if they also include that video.

Thanks in advance
