title: Alternative to INDIRECT
body: <p>I'm using the INDIRECT function to fetch data from another table sheet.
  The direct way would be "sheetname!A5". I need it dynamically, so the sheetname is also part of the table, using indirect "indirect("'"&amp;G$1&amp;"'!A5"), whereas G1 contains the sheetname works fine.</p>
  
  <p>INDIRECT is horribly slow, which outperform my project because I need a lot of fetches.  </p>
  
  <p>Is there a less powerful / more performant function to fetch data from variable sheets?</p>
