Load Test for the Test Suite

Is it possible to create a Load Test that uses all the Test Cases in a Test Suite? Maybe I'm missing something but it seems that the LoadTest is under each TestCase.

For example, if I have a Test Suite that has TestCaseA, TestCaseB, and TestCaseC, I would like to have a Load Test that uses each of the TestCases as part of the load test. Am I missing something?

Thanks
