Is it possible to add toxics via the json configuration file

[4sJackBurridge]

It is possible to populate toxiproxy with the -config option:

[
  {
    "name": "web_dev_frontend_1",
    "listen": "[::]:18080",
    "upstream": "webapp.domain:8080",
    "enabled": true
  },
  {
    "name": "web_dev_mysql_1",
    "listen": "[::]:13306",
    "upstream": "database.domain:3306",
    "enabled": true
  }
]

Is it possible to include toxics such as latency?
