Add test cases to an exisiting folder using Excel Add-in

Hello,

I have 3 levels of sub-folders for my test cases.  I'd like to use the Excel Add-in to add more test cases to the existing folder structure.

When using the SpiraImportTemplate, putting test cases into folder structure (that already exists in Spira)  will create a new folder with the same name as the existing folder if the TCID is empty.  However, folders do not an TCID assigned to them.

Using the Excel Add-in, how do I add new test cases to an existing TC folder structure ?

Thanks
