How Can I Run A TestNG TestSuite Without An XML File?

I want to specify my TestNG tests in Java and not in xml, similar to how I can do it with JUnit;

@RunWith(Suite.class)
@Suite.SuiteClasses({
    TestOne.class,
    TestTwo.class
})
public class JUnitTestSuite {
}

Stackoverflow seems to think that this is a problem with the IDEA plugin

 Is there a way to do it in IDEA?
