自动创建目标表单数据时使其跳过发起节点

//状态改为进行中
                targetBo.Status = H3.DataModel.BizObjectStatus.Running;
                string instanceId = System.Guid.NewGuid().ToString();

                    targetBo.WorkflowInstanceId = instanceId;
                //目标表单创建须在目标表单创建之前获取到WorkflowInstanceId ，并把状态改为正在进行中
                targetBo.Create();

                //对付款单进行流程操作，使其直接跳过发起人节点
                H3.Workflow.Instance.WorkflowInstance wfInstance = this.Engine.WorkflowInstanceManager.GetWorkflowInstance(targetBo.WorkflowInstanceId);
                if(wfInstance == null)
                {

                    string workItemID = string.Empty;
