Ensure Reporter can report multiple percentiles on the same report

Is your feature request related to a problem? Please describe.

In a project I'm working on there are several Non-Functional requirements, where Create and Update times are based on a 99 percentile but Search and View are based on a 95 percentile.

Describe the solution you'd like

Check the reporter can report result names based on both percentile figures, and if not update reporter to be able to do this.

Additional context

NFR 09 99% under 3 sec - Create
NFR 10 99% under 3 sec - Update
NFR 11 95% under 9 sec - Search / View
