Can I emulate user interaction that span multiple request (within single conversation)?

I know I could always do something like this.

new ComponentTest() {

         protected void testComponents() throws Exception
         {
            login();
            fillForm1();
            fillForm2();
            validateResult();
         }    

      }.run();

But I think it would be great if i can do it like

new FacesRequest() {
     protected void invokeApplication() throws Exception {
          login();
     } 
}.setConversationId("1").run();

new FacesRequest() {
     protected void invokeApplication() throws Exception {
          fillForm1();
     } 
}.setConversationId("1").run();

new FacesRequest() {
     protected void invokeApplication() throws Exception {
          fillForm2();
     } 
}.setConversationId("1").run();

new FacesRequest() {
     protected void invokeApplication() throws Exception {
          validateResult();
     } 
}.setConversationId("1").run();

Is there currently any way to do something like that?
