Custom Report for TestSuite with DataSink

I'm looking for some help generating a custom report when generating a TestSuite Report, and including information from DataSink's that are in each TestCase.

I have successfully been able to generate custom reports for TestCase's that take information from a DataSink, using the DataSink Reporting Tutorial (http://www.soapui.org/Reporting/using-t ... asink.html).

I have been unable to customize a TestSuite report that includes information from the TestCases DataSinks.

What are the 'magic' bits of code that need to be included in the report and subreport code?
