How to import multiple values in category with RQMExcelimporter?

Hello,
I using RQM 6.0.2
I have a category defined on a Test Case form. There are several values possible for it
I'm using RQMExcelImporter to create the test cases.
I would like to have a different category value imported for each TC.
With the .CFG I have, all the TC are created with the same value.
Extract of CFG
==========================================================================================
(cfg description to create test script not listed here)
// we want to use the data we got for each test script to create a test case
testcase.ID=testscript.XLSArtifactID

// by referring to the testscript's field instead of the column that data comes from
// the tool will also create links to each of the test scripts.
testcase.dc:title=testscript.dc:title
testcase.dc:description=testscript.dc:description
//Set categories
testcase.category term="Test Case Category".value=J
==========================================================================================
For my understanding the value should be pickup from the cell at column J, current.row
In my case only the value from the last row is pickup .
Therefore all the Test Cases are created with the same value.

Is it possible to do that?*
Thank you in advance for your answer.
