Translating MQTT-Topics globally

Configuration

Hi,
i created some mqtt-entities manually in my mqtt.yaml.

#mqtt:
  sensor:
  # Anwesenheit Michael S20MNI
    - name: "AnwesenheitMichaelOPE"
      state_topic: "owrtwifiOPE/status/mac-xx-5d-8f-a0-14-xx/event"
      value_template: > 
        {% set map = {
          'new': 'on',
          'del': 'off',
        } %}
        {{ map[value] if value in map else 'error' }}
      icon: mdi:account-outline
    - name: "AnwesenheitMichaelAP1"
      state_topic: "owrtwifiAP1/status/mac-xx-5d-8f-a0-14-xx/event"
      icon: mdi:account-outline
    - name: "AnwesenheitMichaelAP2"
      state_topic: "owrtwifiAP2/status/mac-xx-5d-8f-a0-14-xx/event"
      icon: mdi:account-outline
    - name: "AnwesenheitMichaelAP3"
      state_topic: "owrtwifiAP3/status/mac-xx-5d-8f-a0-14-xx/event"
      icon: mdi:account-outline

As you can see, I need to translate the state_topic new=on and del=off.

My question is: Is it required to add the “set map” statement to each entity (*AP1, *AP2…) or is there a global approach to create a map like above?
