+| 会签         | 同一个审批节点设置多个人（如 A、B、C 三人，三人会同时收到待办任务），需全部同意之后，审批才可到下一审批节点                            | ✅    |
+| 或签         | 同一个审批节点设置多个人，任意一个人处理后，就能进入下一个节点                                                     | ✅    |
+| 依次审批       | （顺序会签）同一个审批节点设置多个人（如 A、B、C 三人），三人按顺序依次收到待办，即 A 先审批，A 提交后 B 才能审批，需全部同意之后，审批才可到下一审批节点 | ✅    |
+| 抄送         | 将审批结果通知给抄送人，同一个审批默认排重，不重复抄送给同一人                                                     | ✅    |
+| 驳回         | （退回）将审批重置发送给某节点，重新审批。可驳回至发起人、上一节点、任意节点                                              | ✅    |
