Access testStepResult from custom TestStep

Hi. I'm trying to create custom test step that will collect some information from all test step results e.g. response time, status and so on. I was able to create test step itself, it works fine. But i have to access WsdlTestSuiteRunner from [public TestStepResult run (TestCaseRunner testRunner, TestCaseRunContext context)] method to use getResults() and iterate thru all TestCaseRunners to get results for all test steps.
But i can't find how to access WsdlTestSuiteRunner at this point. Could you give me advise about this? Or maybe some other way how to reach my goal?

Thanks
