Need to run specific Test Step through JUNIT test

Hi,
I Need to run specific Test Step through JUNIT and I only saw a way to run a whole Test Case (which obviously has multiple test steps).

This is my code:
assertNotNull("Please set the SoapUI project file", soapUIProject);
        WsdlProject project = new WsdlProject(soapUIProject.getAbsolutePath());
        printProjectTestInfo(project);
        TestSuite testSuite = project.getTestSuiteByName(suiteName);

        TestCase testCase = testSuite.getTestCaseByName(caseName);
        testCase.addTestRunListener(this);

        // create empty properties and run synchronously
       
        TestRunner runner = testCase.run(new PropertiesMap(), false);
        Status status = runner.getStatus();
