Excel to RQM

I'm running into a issue of linking test scripts to test cases during excel export into RQM. When I use the line testcase.XLSLink=testscript in the config file, it links every test script to every test case. Is there any way to make that line (testcase.XLSLink=testscript) more specific, where I can
tell it what scripts to link to specific test cases?

If you have a one-to-one mapping between test scripts and test cases then you can use the self-reference link. Here you can say

testcase.dc:title=testscript.dc:title

for example, you can choose any field that you want to link on. This statement says: make the current test case's title the same as the testscript's title, and make the testcase link to the testscript.

From the documentation...
To define a self reference, simply put in the information from the left side of the equals from a previously defined line:

testscript.dc:title=G

testcase.dc:title=testscript.dc:title

Note: Self references are used to create artifacts that will use data already being used by another artifact and will create a link to that artifact.

Other, than this you'd need to organize the worksheets so that there was one testcase and n testscripts. Then the testcase would reference all of the scripts on that sheet. The next sheet would need to have the next testcase.
