WF - custom activity c#

Cześć,

Napisałem takie activity:

            Implementation = () =>
                new TryCatch
                {
                    Variables =
					{
						//Variables
					},

                    Try = new Sequence
                    {
                        Variables =
						{
							//Variables
						},

                        Activities =
						
							//new Act1,Act2,Act3,Act4
							
							//ACTIVITY PICK A
							new Pick
							{
								Branches =
								{
									new PickBranch
									{
										//Trigger = T1

										Action = new Sequence
										{
											Variables =
											{
												//Variables
											},

											Activities =
											{
												//new Act1A,Act1A,Act1A,Act1A
												
												new Sequence
												{
													Variables =
													{
														//Variables
													},

													Activities =
													{
														//new Act1B,Act1B,Act1B,Act1B
													}
												},

												new Pick
												{
													Branches =
													{
														new PickBranch
														{
															//Trigger = T2,

															Action = new Sequence
															{
																Activities =
																{
																	//new Act1C,Act1C,Act1C,Act1C
																}
															}
														},

														new PickBranch
														{
															//Trigger = T3,

															Action = new Sequence
															{
																Activities =
																{
																	//new Act1D,Act1D,Act1D,Act1D
																}
															}
														},                
													}
												}
											}
										}
									},
									
                                    new PickBranch
									{
										//Trigger = T4,

										Action = new Sequence
										{
											Activities =
											{
												//new Act2A,Act2B												
												
												//go to ACTIVITY PICK A
												
											}
										}
									},
									//...

Potrzebuję po wykonaniu activity //new Act2A,Act2B wskoczyć do ACTIVITY PICK A. Czy jest na to jakiś sposób? Na msdn jest niewiele informacji na ten temat. Może ktoś się spotkał z podobnym problemem ?
