Custom alarms sound for sleep/wake up under Health app

In clock alarms, sleep/wakeup is controlled by the Health app; your schedule, next bedtime, and wake-up alarm. Under the wake-up alarm for the Health app, there are sounds & haptics, 7 sounds to select one for the wake-up alarm, here is the list;

early riser

first light

helios

orbit

birdsong

droplets

sunny

springtide

bright-eyed

I used all of them and want to have for example "iPhone Opening (trap remix)" from iTunes Store. I did download the trap remix and I can use it in any alarm but cannot be used in the sleep/wakeup alarm from the Health app.
