Anyone know how to change Mate 9 alarm tone?

[Gob Shite]

Anyone know how to change Mate 9 alarm tone? Only method I can find is to open the clock, open an alarm, and click alarm tone, and click music.
This fall's down because it list 10,000 tracks with no method of navigation and listed by "id3 track name". Even tried editing an id3 tag to "...1" to appear first but the stupid phone does not refresh the list. Tried resetting the clock memory but still no joy.

Are you just trying to find the preinstalled alarm tones, or you want to use one of your music tracks?
