Add Test Cases the I2C Studio

Can I add my own test cases into the I2C Studio GUI for the Negative Tester?
Typically the users of the Negative Tester are using the GUI for their first tests. Afterwards the customers typically write the own test cases use the I2C APIs. Most users integrate these test cases into their own testing framework, which communicates with the Negative Tester on one side and with the DUT on the other side.
