Im probably being really dumb/blind, but I can't figure out how to configure the "Report Selected with Children" report in QCv10.

I select/highlight the Requirement, go to Analysis > Reports > Report Requirement with Children and it opens the report in a new screen. But it's displaying a heap of fields I dont want to see.

In previous versions of QC I was able to click on the green "cog" (Configure) and customise the fields. How do I do a similar thing in QCv10???
