Customize Default Fault format

[#1]

By Fault Errors responded in below format. Is there anyway we can customize the format. I want to make consistent fault response between my target server and apigee' fault. Thanks.

{
  "fault": {
    "faultstring": "Invalid Id",
    "detail": {
      "errorcode": "400",
      "info": "Contact: support@support.com"
    }
  }
}
