Video library import/play function within Screvi

I would like the ability to create a dedicated video library for a specific subject. For example, I might want a library containing only the MIT Computer Science course videos. If you look into their youtube channel they have different libraries for different courses. Currently, I can subscribe to an entire YouTube channel using its RSS feed, but I'd like the option to organize videos into custom libraries and assign each library its own title. All highlights created from videos in that library would then be grouped under that title. Readwise Reader has (or at least had) a similar feature for organizing/playing content, and I found it very useful.
