How do I create a report on test cases showing who created them?

I'd like to run a report on our test cases that groups them by who created them so that we can better align which folder they are in (based on the area of the product that person is most likely working on). 

The reports, when exporter, do show who created a test case, but I can't find a report that shows me ALL of the test cases.   Is there a way to report on Test Case "created by" - and filter by person? 

I've tried various exports of lists of test cases, but I can't define which fields to show and it doesn't export the name of the person who created.  

I've checked out some of the reports, but they don't actually export a list of every single test case in our repository. 

thanks!
