Multiple Keystores - SSL Settings

Hello, Currenltly in SoapUI (open source version) there is a Global Setting to specify the SSL key store and we can use that key store for all of the tests with in the project scope. But, what if I need to specify different SSL keystores at each test case level? For example say that each of my test cases need to refer different keystores. I don't see a straight forward way to set different key stores.

Please let me know if there is a way of doing this.

Thanks
