Is it possible to run the selected configuration without persisting it?

Hi,

Regards to an Android Studio plugin,
I want to run the "selected/activty configuration" with temporary parameter (like setting the "launch Activity").
I managed to do it by the attached code, but the change is persisted.
Question:
  Is it possible to achieve the goal wihtout persisting it? Thanks.

public void testAction(AnActionEvent e) {
    RunManager manager = RunManager.getInstance(e.getProject());
    RunnerAndConfigurationSettings selectedConfiguration = manager.getSelectedConfiguration();
    RunConfiguration conf = selectedConfiguration.getConfiguration();
    if (! (conf instanceof AndroidRunConfiguration)) {
        return;
    }

    AndroidRunConfiguration anConf = (AndroidRunConfiguration) conf;

    // change the target Activity -- Note: it will change the stored configuration
    anConf.setLaunchActivity("com.example.app1/com.example.app1.MainActivity");

    Project project = e.getData(PlatformDataKeys.PROJECT);

    ProgramRunnerUtil.executeConfiguration(project, selectedConfiguration,
            DefaultRunExecutor.getRunExecutorInstance());
}
