Execute shell code directly from automation

Currently you have to define a shell_command and then call it from automation like

  - service_template: >
      {% if is_state("input_select.radio_station", "RelaxFM") %}
        shell_command.onkyo_play_relaxfm

Expected improvement like below (crude example)

  - shell_command_exceute
    data_template: >
      {% if is_state("input_select.radio_station", "RelaxFM") %}
        "/usr/local/aplay -radiofm"

Yes. It would be convenient. Also it is necessary for scripts
