[Question] Select by file name?

[Obegg]

Example:
-- Folder name: Movie
--- Movie.mkv
--- Movie_eng.ass
--- Movie_chi.ass
--- Movie_spa.ass

Is it possible to auto-select subs with "eng" as their file name?
In some cases those are the only indications to which language the subs are.

This option here will select such external files if they do not contain a proper language code:

    {
        "alang": "*",
        "slang": "und",
        "condition": "sub.external and (sub['external-filename'] or ''):lower():find('eng') ~= nil"
    }

Thank you!
