MQTT Device Tracker in Zone

Hi all,
i have this code for track 2 bluetooth-le dongle

  - platform: mqtt
    source_type: bluetooth_le
    payload_home: 'presente'
    payload_not_home: 'not_home' 
      giulietta_andrea: 'tile_giulietta_andrea'
      golf_marco: 'tile_golf_marco'

Now when the payload is “presente”, home assistant set me to Home. How i can set the payload “presente” to track me in a different zone, alredy in homeassistant?

I have tried with "“payload_MYZONE” but whitout success.
