Import test cases from EXCEL file into JIRA

Hello all.

When importing test cases from an Excel file, it's possible to specify different fields in the mapping between Excel and JIRA. It's possible to specify e.g. Description, Fix-Version, Label - so that these fields will be populated in JIRA with data from the Excel file, when importing a test case. My question is as follows:

How to specify more than ONE label, in the excel spreadsheet, so that JIRA interprets it as 2 or more labels to be added to the individual test case which is imported from Excel? It's easy to import and map ONE label for a test case in JIRA, originating from Excel. But is it possible to add 2 or more labels in JIRA from a test case which is imported from an EXCEL spreadsheet?
