Functionality is available by default starting with JMeter version 2.13

The behavior is controlled using the following properties:
aggregate_rpt_pct1=90
aggregate_rpt_pct2=95
aggregate_rpt_pct3=99
If you do not see percentiles like the one above, in the Aggregated Report - add the above lines to the user.properties file.
Note:
- This approach will not work in JMeter versions earlier than 2.13
- You will need to restart JMeter to select properties; dynamic changes will not work.
