title: Multiple extends or multiple stages?
body: <p>I want to have a CI to deploy two commands ("bash X" and "bash Y") on different production servers (server 1, server 2, server 3, etc.).</p>
  
  <p>I looked for multiple stages but it don't seems to answer my question.
  I don't really care if it runs in parallel or B after A. (the manual section is for debugging)</p>
  
  <p>I don't know how to do it : I tried with multiple extends but it only takes the last one (bashB) in my pipeline.</p>

      - .bashB
    variables:

  </div>
  </div>
  </p>
  
  <p>I just want to be able to deploy bashA and bash B on X servers (I just took 2 servers for example).</p>
