Hi, working with ScenarioFramwork and all the Hierarchy can be a bit od if you have a lot of Prefabs in your Mission. For example:

If you have several HQs on the Map, where every HQ have more then 30 Objects/Prefabs, you need to build your own Prefab with all of then in one. So, you can spawn them by a random Slot.

it will be much easier if we can spawn/despawn a complete Layer or Area of Prefabs with the ScenarioFramwork.

For Example:

You create several Objects on the Map and moving them into a specified Layer or Area.
Now you can trigger only the Layer you need for the current mission.
So, you do not need to pack all the Objects into one Prefab and spawn it with a Slot.
