alexa_media_player: YAML macros do not work in HA service call

In the documentation the target setup in notify is :

  - service: notify.alexa_media
    data:
      data:
        type: tts
      target: 
        - media_player.downstairs
        - media_player.upstairs

or target

  target: 
    - media_player.downstairs

or target:

target : - ‘{{ states… }}’ but don’t work if i create a macro to pass a media:player target: >- {{ macro ecc ecc }} with resoult - media_player.downstairs

Is possible to add a templete in target : ??? Many thanks!
