How to combine different datasinks into one datasink

Part of the solution i found

def populateFinalDataSink (DataSink dataSink)
{
def dataSinkTableModel = dataSink.getData()
def dataSinkFinal = testRunner.testCase.testSteps["DataSink"].getDataSink()

for (int i=0; i<dataSinkTableModel.getRowCount(); i++)
{
def values = new StringToStringMap()
values.put("TestCase", dataSinkTableModel.getValueAt(i,1))
values.put("Description", dataSinkTableModel.getValueAt(i,0))
values.put("ItemID", dataSinkTableModel.getValueAt(i,2))
values.put("Result", dataSinkTableModel.getValueAt(i,3))
dataSinkFinal.save(testRunner, context, values)
}
}
