column merge in .cfg file. in RQM 6.0.2

I am using ExcelImporter (6.0.2) to export the testcases and test scripts. I want to concatenate the values of column L, I, J and column N from the  excel testcase sheet and assign it to Testcase Description.  My cfg  file  contents are:--



testscript.steps.type="execution"
testscript.steps.description=L & "<br> Tcode:" & I & "<br/> RICEFW: " & J & "<br/> Input Data: " & N

This is resulting in the Description with one line. I want to merge in such a way that it should come in line by line :
Instead - LIJN
it should come in
L
I
J
N
