It would be great if there was a clear, obvious indicator somewhere on an existing report of whether it's a Row Report or a Sheet Summary Report. Currently, the only time that distinction is expressly stated is when you create the report and have to pick one.
For advanced users, it's generally clear what kind of report it is from what you do and don't see [though even experienced users in my company rarely use Sheet Summary Reports and as such don't know the difference without research]. For less advanced users, it looks just like a normal report that doesn't show any of the things it's supposed to that can't be corrected. I feel like there should be some way to see the Report Type, even if you can't change it on the fly.
Since Row Reports are the most common by far, maybe it only makes that distinction if you select a Sheet Summary Report. Maybe that indicator goes where the Report Scope button is on a Row Report. Maybe it just goes on the Properties page. My point is that this could stand to be a lot more clearly indicated.
