How to pass all defined variables in Automation to the script called in the same Automation action?

Configuration
1

I am trying to pass all the defined variables in Automation to the script called in the same Automation action without again declaring them separately in the in the data: part. Can anyone help me out please?

Automation:

alias: Music Automation
description: Music Automation
trigger:
  - platform: time_pattern
    seconds: /5
condition: []
action:
  - variables:
      status_keys: "{{ ['off', 'idle', 'paused'] }}"
      playback_volume_key: music_automation_playback_volume_
      spotify_account_slug: home_assistant
      spotify_uri: spotify:playlist:37i9dQZF1DXdwTUxmGKrdN
  - if:
      - condition: time
        after: "09:00:00"
        before: "00:00:00"
    then:
      - service: script.turn_on
        target:
          entity_id: script.cast_spotify
        data:
          variables:
            status_keys: "{{ status_keys }}"
            spotify_account_slug: "{{ spotify_account_slug }}"
            spotify_uri: "{{ spotify_uri }}"
            target_id: >-
              {% set max_vol = states.input_number | selectattr( 'entity_id',
              'search', playback_volume_key ) | selectattr( 'state', '>', 0 |
              float | round(2) | string ) | map( attribute = 'state' ) | map(
              'float' ) | list %} {% set max_vol = max_vol | min if (
              states('input_boolean.music_automation_device_selection_by_minimum_volume')
              | string | lower == 'on' ) else max_vol | max %} {% set
              selecteded_device = states.input_number | selectattr( 'entity_id',
              'search', playback_volume_key ) | selectattr( 'state', 'eq',
              max_vol | round( 2 )| string ) | list | first %} {{ dict( volume =
              selecteded_device.state | float | multiply( 0.01 ) | round( 2 ),
              name = selecteded_device.entity_id | replace( 'input_number.'~
              playback_volume_key, 'media_player.' ) ) }}
    else:
      - service: media_player.turn_off

          float | round(2) }}
