Thanks for clarifying, Jade. Grouping by pupil names was a feature we had trialled before. I removed it because I wasn't sure anyone would want it, given Cohorts > Tables does that in some way already. Also, I worried that it could be a little confusing if the report tried to say "% of pupils at/above expected" when there's only one pupil. "Average attainment" is also a bit odd, since it's just a single assessment.
However, I can see from your screenshot why you'd like the option again. I'll need to discuss with the team!
