title: Way to change default start-date to a logic value at slider interface?
body: <p>I am using the slider interface to select date interval (<code>date1</code> to <code>date2</code>), as illustrated below. I need that the default value for <code>date1</code> is &quot;now()- 20 days&quot;... It is possible to do this?  Perhaps using DAX, but how to do this?</p>

  <h2>NOTES</h2>
  <ul>
  <li><p>a global (page) filter with the logic &quot;last 20 days&quot; is a workaround but <strong>it is not a solution</strong> because reduce the slider domain. I need to use all the dates in a big range... The <em>set default <code>date1</code></em> logic is only &quot;to be friend with the user&quot;, offering a good start view of the dashboard, but not eliminating the big range.</p>
  </li>
  <li><p>(edited after @StelioK's answer).  I need that the online dashboard starts with this &quot;pre-selected date&quot;... If I put with the mouse the slider in the position that I need (middle), save and publish the dashboard, ok, every user will open it as &quot;default state&quot; (open dashboard with slider in the middle). But I can't do it every day and all my life, I need to automatize the process.</p>

  <li><p>Analogy: the <a href="https://stackoverflow.com/a/3518011/287948"><code>selected</code> attribute of HTML interface</a> offers a way to change default start-option.</p>
