Suggestion: Transcribing playlists.

Could there be a way to expand upon this so that it'll transcribe and learn from multiple videos?

Such as: https://www.youtube.com/watch?v=rmVRLeJRkl4&list=PLoROMvodv4rOSH4v6133s9LFPRHjEmbmJ 

Then we could look at asking it questions about an entire course rather than an individual video.
