title: Is it possible to create a single pdf from multiple Google spreadsheets?
body: <p>I am able to create a pdf from a single Google spreadsheet sheet <a href="https://stackoverflow.com/questions/21997924/export-or-ptrint-with-a-google-script-new-version-of-google-spreadsheets-to-pd">using this code</a>.</p>
  
  <p>Is it possible to tweak this code to allow multiple sheets from different spreadsheets to be merged into a single pdf?  Or would I need to take an entirely different approach?</p>
