Custom Notification sounds?

Is this possible with something like this

service: notify.mobile_app_sm_g973f
data_template:
  title: Doorbell
  message: Someone is at the front door
  data:
    image: >-
      https://ha.deanfourie.me/local/images/doorbell/doorbell_{{ now ().year }}{{ now ().month
      }}{{ now ().day }}_{{ now ().hour }}{{ now ().minute }}.jpg
    clickAction: /lovelace/cameras
    sound: "https://ha.deanfourie.me/local/sounds/notifications/doorbell.wav"

To push a sound to be used as a notification sound? Is it possible to use custom notification sounds depending on the notification triggered?

Thanks

The only way I’m aware of to customize notification sounds is by specifying a unique notification channel and then customizing the sound on your device for that specific channel.

How would you emulate that in Node Red? Currently I manage notifications like this:

Unfortunately no idea, I’ve never used Node Red.
