Add an features to tag for Audio-Description

Hello, I would like to know if it would be possible to add a function that detects (AD) or (DV) in the name of a series folder and adds a tag to indicate that the series is available with audio description. Thank you in advance.

And what if there are both regular and descriptive audio tracks in your file(s)?
Marking descriptive audio per file or folder title of the whole video is not very flexible.

Audio cannot be in a separate file, like a subtitle can.
