title: lazy-loading doubleclick ads versus enableSingleRequest()
body: <p>In an attempt to increase Active In-View metrics, I'm trying to defer a display ad call (<code>googletag.display('ad-' + adLocation)</code>) by wrapping it in an 'in-view' check (using jquery.inview), but this only seems to work if I disable <code>googletag.pubads().enableSingleRequest();</code> Am I correct in understanding that <code>enableSingleRequest()</code> is overriding my calls to <code>googletag.display</code>?  </p>
  
  <p>To clarify, <code>enableSingleRequest</code> is necessary in order for us to serve guaranteed roadblocks, but we also need to ensure that ads are only being served when they are in-view.  Is this even possible?</p>
