title: Two date parameters while connecting Google Data Studio with BigQuery
body: <p>As I read in <a href="https://support.google.com/datastudio/answer/9002005" rel="nofollow noreferrer">this link</a> "Report viewers can't modify data source parameters directly. However, if you've enabled date parameters for a BigQuery data source, and your report includes a date range control, viewers can use that control to request different starting and ending dates from the BigQuery data."</p>
  
  <p>I'm facing a situation where I need to filter two periods at the same time and over the same data source:</p>
  
  <ul>
  <li>Period where users installed my app.</li>
  <li>Period where users made actions.</li>
  </ul>
  
  <p>For now, Data Studio permits only one date parameter in customized queries for BigQuery (DS_START_DATE, DS_END_DATE). But what if I need an additional date parameter? Is there a solution to this need?</p>
