title: Google Analytics: how to use specific events in dimension grouping?
body: <p>How can I group by specific event values and exclude any other events?</p>
  
  <p>I considered I could filter a custom report by the range of allowable event values, but I can't do this since 1) I seem to be an 8-filter limit and 2) I'm afraid the report would lose pageviews from users who don't see the report.</p>
