Way to exclude/ignore directories?

[iconoclasthero]

[ I looked more closely at the documentation this time. ]

Various programs have ways to prevent directories from being used/processed by them. E.g., mpd has .mpdignore files, GNOME tracker has .nomedia, .trackerignore, etc., files. fd has .fdignore. There are also command-line ignore commands for e.g., fd and find.

Is there any such mechanism in rgain3? Could there be? It would be nice if i could ignore processing of temp/incoming directories, etc.
