title: Data studio bug - predefined date range unable to change in view mode
body: <p>Seems that I found a bug in DataStudio, unless it is a feature :)</p>
  
  <p>When I created a report where I made default date range : e.g. last 28 days,
  Then when somebody or I  want in view mode change the default date setting :  e.g. last 7 days, it still show the predefined time scale.
  Any idea ?</p>
