As shown in the figure above, when the node "Team Leader Assignment" returns to the "Business Assignment" node, the business assignment needs to re-assign a new "Team Leader Assignment". At this time, it is necessary to call the revision interface to complete the creation of multiple instances of parallel branches. If "A" in the figure above returns, after reselecting the group leader assignment, it may be B, C and the new parallel instance M (here it is just an identifier, after K).
