Allow adding of multiple custom headers through environment variables

Hi.

Consider Http client request in a file eg: login.http as follows

POST {{host}}/api/login
Content-Type: application/json
MYAPP-IP: 111.111.111.111
MYAPP-PROD: JZW
MYAPP-SID: 98232fakesessionid800

{
  "username": "{{teacherU}}",
  "password": "{{loginAppKey}}"
}

MYAPP-IP, MYAPP-PROD and MYAPP-SID are my custom headers that are common to all my API request.

I am trying to add a variable to represent my headers to my environment file http-client.env.json like below:

{
  "development": {
    "host": "http://localhost:8080",
    "teacherU": "someuser@myapp.com",
    "teacherP": "EwBolDEpISESTrEwBolDE",
    "loginAppKey": "E+jFR8jzDL86ne+OXfplZqLE+jFR8jzDL86ne+OXfplZqLPco4FFW0JtDvjxe8lYrg/EA0PxD9oDJCrwfwSVCpceZNP5sYsD8MMsHstKbhLix7BVKgQ16b1SgIy7Ve7zpIw6ySbAahAo3eXk9jUaSk1hvOvobXIOpva23Nrtxuass8buRT8IxwbmzdWyDrds0htdtd5",
    "headers": "Content-Type:application/json \n JZ-SID:98232fakesessionid800 \n JZ-IP:111.111.111.111 \n JZ-PROD:JZW"

  }
}

So that I can include the header in my request as below so that all my headers come from my variables. This does not seem to be possible. :

POST {{host}}/api/login
{{headers}}

{
  "username": "{{teacherU}}",
  "appKey": "{{loginAppKey}}"
}

Is there a way to achieve this so that all of the following conditions are met:

• The headers that I always want to include are defined en-masse in my variables file.
• If I need to remove/add new custom headers, I can make the change in the env variables file and my requests automatically pick up the changed headers.
