In the "job output" tool there's a button called "When finished…" with which you can tell the GUI to execute a pre-configured action after the currently running job (or the whole queue) has finished. Using that button is what I meant.

What you cannot do, at the moment, is go to the "job queue" tool and execute a pre-configured action from there, e.g. for a completed job.

For your use case I'd simply write a script that iterates over all files in a certain folder, uses "mkvmerge --identification-format json --identify currentfile.mkv" in order to query track IDs and properties and then calls "mkvpropedit currentfile.mkv --edit track:… --delete name --edit track:… --delete name…" for all tracks that do have names set. That's assuming all of your files for a specific season (or show) end up in the same folder, but no other files are present in said folder.
