Why can't Studio capture directly Mac audio device?

Shy is there no functionality for Studio to directly capture Mac audio device? For example, if I am playing, as part of my lecture an example youtube video, the audio of that video is only recorded 'through the air' via the Mac's microphone. This results in poor quality of the final screen capture audio. I understand that Studio is based on screencast-o-matic. This has a paid-for upgrade to capture mac audio directly. But this is not integrated into Canvas studio which operates with only the free version of screencast-o-matic.
