How to output DataSink data to report from testrunner?

The project is invoked in my CI environment in an automated fashion using groovy as the harness (called from Gradle). I have a datasink test step with the sink type of SubReport that I was hoping to merge into the jasper reporting built into soapUI.

Temporarily what I've done is export the datasink properties to my own html data file using a groovy script but the solution relies on my own custom formatting and isn't as organized as having a single all-encompassing report.
