title: Firebase hosting deploy to other site
body: <p>how to deploy to other firebase hosting sites defined within the same project.
  I created multiple firebase hosting "sites".
  The command</p>
  
  <pre><code>firebase deploy
  </code></pre>
  
  <p>however always deploys to the first one.
  How can I specify that the static files get deployed to another "site" (and domain).</p>
  
  <p>Thanks</p>
