We often need to determine how many unique items (page names, sections, products, etc) contributed to the "total" metric in a report.
We can sometimes try to page-forward some significant number to find the end -- thanks for that -- but it should be a something shown at the bottom of the page near the total.
Had already posted this here:
Oh sorry, I had forgotten about that one -- and I had even promoted it!
I was really pushing for adding it to ReportBuilder but then remembered it wasn't in the UI either.
I'll restate as one of two improvements to ReportBuilder.
