Better notifications to mobile device? New phone = lot of edits

I have a bunch of automations using notify.mobile_app_old_phone that I now have to change to notify.mobile_app_new_phone. Unfortunately, I can neither edit all automations at once via yaml (unlike the frontend), nor can I find a list of which automations are sending notifications to my old device. I have to click into each and every one just to change:

action:
  - service: notify.mobile_app_old_phone
    data:
      message: This is a notification

to

action:
  - service: notify.mobile_app_new_phone
    data:
      message: This is a notification

I shouldn’t have to deal with this again for two years, but why deal with it at all? What’s the better way to do this?

Make a notification group. Then point all your services to that group. That group will just contain your mobile device, or multiple devices. When you change your phone, update the groups device(s).

Notification group seems doesn’t work? “No matching entities found”.

They can only be created in yaml. The ui version only accepts notification entities where the Yaml version uses notification services.
