title: Is it possible to merge multiple Google Docs into one single Google Apps Script project?
body: <p>Suppose we work with 5 different documents in Google Docs. It could be Sheets, Slides or Forms, but I'm working with Docs.</p>
  <p>Each document have the same Google Apps Script project i.e. the code is identical (it is a very simple project - it replaces some text with another).</p>
  <p><strong>Is there a way to combine these 5 scripts into one single project that includes the 5 docs?</strong> I guess this will be useful because:</p>
  <ul>
  <li>When collaborating, Google don't have to ask us for permission to execute the script several times.</li>
  <li>It is more easy to edit the script (and not 5 times).</li>
  <li>If the script needs to be run on multiple docs at the same time, it is only done once.</li>
  </ul>
  <p>Perhaps merging them into one project will cause conflicts, but the project is pretty simple.</p>
  <p>Scheme of what I want:</p>
