title: Auth options in environment
body: <p>I have different environments for an api (different servers, dev, staging, live). I can use curly brace placeholders for say the username, but I still need to replace the auth headers on each stored request.</p>
  
  <p>Is it possible to run a post environment script that automatically updates headers or does what ever needs to be done?</p>
  
  <p><em>Comment:</em> I can use the generated header value from the environment, that is something like <code>Basic blabla</code> which is then referenced in the requests. Still wondering whether a more elegant way is possible</p>
