title: JMeter - Assert based on percentile
body: <p>I know JMeter have some custom properties that store 90, 95 and 99 percentile (if I'm not wrong, aggregate_rpt_pct1, 2 and 3 respectively).</p>
  <p>My question is: Is there any assertion where I can retrieve this property to validate against a expected value? Currently I'm running locally, but will have it running on Azure Devops eventually.</p>
