title: Tableau percentage increase toggle for multiple columns
body: <p>I have 3 fields: |CNTD(OrderID)|Charged Amount|Paid Amount|</p>
  
  <p>I would just like to create a toggle where the end user can just input a percentage number to show percent increase accross the board for those fields. I will clone the existing fields as new columns. </p>
  
  <p>I would like my result to like this:</p>
  
  <p>% Increase Input: <code>10</code>%</p>
  
  <blockquote>
    <p>|CNTD(OrderID)|Charged Amount|Paid Amount||CNTD(OrderID)|ChargedAmt|Paid Amt|</p>
  
  <pre><code>100           $10000        $1000        110          $11000     $1100
  </code></pre>
  </blockquote>
  
  <p>Thanks</p>
