Better place to post Questions about computing Challenges

tl;dr I think there should each computing Challenge should have its own linked Discussion area rather than having to post Questions below a video or article.
--------------------------------------------------

Because none of the computing Challenges has a Discussion area, users tend to ask Questions about a Challenge under the previous video or article.  This isn't great (because Questions about the video/article get drowned out by Questions about the Challenge), but has usually worked ok. Unfortunately, some of those videos/articles are also used in other courses.   
For example, when someone wants to ask a Question about the Python Challenge: Environmental footprint, they'll probably post it under the video 'Algorithmic bias'.  When I went to answer such a Question, the video showed up as part of the course 'AP®︎/College Computer Science Principles', so I had to separately open the Python course and search for the challenge the user was asking about.  This makes it less likely someone will answer such Questions.  I would imagine that the users in the Computer Science Principles class are confused by Questions about a Challenge that doesn't exist in their course. 
Having this overlap is a problem because Challenges don't have their own Discussion area.

Does anyone else agree that Challenges should have their own area for Questions?
