Envoy escape_hatch

I’m using Consul escape_hatch feature to configure envoy access logs. We’re not using Docker for this. Adding something like this in escape_hatch:

envoy_public_listener_json= <<EOL
             {
                "name": "local_agent",
                "address": {
                  "socket_address": {
                    "address": "0.0.0.0",
					"port_value": 20002
                  }
                },

Is there a way to not hard-code port_value since we need envoy access logs for every side car proxy?
