  <p>I would like to have as a calculated field in a time series:</p>
  <p>Event Value of (Event Category: Economy, Event Action: Wallet Credits Changed, Event Label: game_session_bet)</p>
  <p>+</p>
  <p>Event Value of (Event Category: Economy, Event Action: Wallet Credits Changed, Event Label: game_session_win)</p>
  <p>So basically a sum of those two event values.</p>
