title: Jmeter - Run multi-threaded users simultaneously without affecting the flow
body: <p>I have a user flow (create base64 header auth > register request > Register > login > sending data) which I want to run simultaneously (100 users).</p>
  
  <p>If I use the Thread Properties as it is, it will run in asynced way.
  Examples:
  User 3 will try to login with token of user 1, user 40 will register with registration header created for user 24 and so on..
  Token for login extracted from base64 process,
  another token is extracted from 'register-request' and used as variable in 'registration' header.</p>
  
  <p>I want first user to register with token created in first register-request and login with token created in base64 process, and so on for next users.</p>
  
  <p>Is there a way to do so?</p>
