It would be great if Groups and Organizations have a “Managed by” field. It should be a text field with autocompletion from the list of users (one or more users can be specified as a managers separated by semicolomn or any other way)
The key result here is an ability of creating some approval/escalation triggers. E.g. if uers requests something, some approval message is automatically generated regarding of the Group/Organization user belong to.
This can also be usable to delegate Group/Organization modification for it’s manager. Or even modification of all child objects for group manager.
