Creating test case from command line

Greetings!

I'm currently parsing an excel, extracting information from there and I want to dynamically create a test case for each line of the excel.

I already have extracted the information, but I have a problem when creating a test case using command line.

For example:

im createissue --type="Test Case" -> throws an error that says : "Can not create an Item of Type Test Case" (?)

but I managed to create a test step using the same command... im createissue --type="Test Step"

Is it not possible to create a test case from CLI ?

Please note that I have searched all the IMS manuals and I found nothing.

Regards,

Adrian.
