From different posts, got your point.
Default report generation is based on the SoapUI/ReadyAPI test case, but not based on the data set used in the test. And every knew this, I believe. However, many questions out there in the forum as users wanted the report differently.
So, now the option is to see if it is feasible that way as mentioned in the question.
Usually, when the test is executed, the tool generates some files for each test and I believe that those artifacts are used while generating the report. But, in case of data-driven, the same test is repeated as many times as the data available and it may stop once a row is failed or data set is complete. In the report, it can take only that as per my understanding.
There is documentation available for custom reporting and also user can write some kind of plug-in if I am not mistaken.
Hope you might have gone thru documentation. Otherwise take a look and see and try the methods suggested and come back with your observations.

Otherwise some one would have pointed. But still worth to look what is the nearest method to achieve it easily.
Remember some plug-in to custom report, but not on top my head at the moment, try searching on the net.
Just curious to know what is the current reporting that is being adopted? Junit, PDF, Allure or something else?
