Restore triggered template images

Would it be possible to restore triggered template images the way triggered binary sensors and sensors are restored?

At the moment a triggered template image requires extra triggers to overcome this. e.g. this

- trigger:
    - platform: time_pattern
      minutes: "/30"
    - platform: homeassistant
      event: start
    - platform: event
      event_type: event_template_reloaded
  image:
    - name: etc...

Could become:

- trigger:
    - platform: time_pattern
      minutes: "/30"
  image:
    - name: etc...
