Single xml junit report file

We are running @Category annotated unit tests with the cp-build-suite plugin.

Currently for every unit test class a test report xml file is created in the test-results directory.
Is there a possiblity that only one big report xml file is created where all the unit tests executed by our suite are present.
The reason why we would like to have one single file is, that we want to view the suite result in the eclipse JUnit view.
