title: SSRS - Show "select all" text for multi value parameter
body: <p>I know how to show all values chosen for a multi value parameter but how do I display just "All" when a user clicks on the "Select All" checkbox? My parameter has a lot of values in it and I don't want them populating in my report which pushes the tablix far down.</p>
  
  <p>Using Report Builder 3.0 here.</p>
  
  <p>Thanks in advance.</p>
