Exclude folders from alarm sound picker

It appears the app displays every sound file it finds on my phone. i have about a hundred audio books and each of those is 1-40 files which litters the list with irrelevant sound choices. If I use the folder option to go to just a single folder, then when I select a sound to test, it just choses it, doesn’t start playing it to test and wait for confirmation that I want that sound like the opening sound picker.

Need a way to exclude folders I don’t want as sound choices so the opening sound picker just shows the ones I do want to chose from.
