Depending on your viewpoint, this could be considered a bug, or a feature request. Currently the results of a data driven load test, where the data modifies the outgoing query string of the HTTP request, the results are all grouped together by the originally recorded URL. The actual URL sent is not shown in the results, nor separated out by actual URL. Customers tend to prefer to see the actual URL in the results and the timing information for each actual URL displayed with its URL in the results.
