    I think it's impossible, but I'd really like to do something like that.

    Well, I'm sad, but thanks. Good to know that though. I don't think I've ever tried it, will keep it in mind.

    I don't seem to be able to do that. Here's the code
    Code (CSharp):
    1. var area = CreateInstance<AreaDataSO>();
    2. area.name = "SubAsset";
    3. AssetDatabase.AddObjectToAsset(area, Selection.activeObject);
    4. AssetDatabase.ImportAsset(AssetDatabase.GetAssetPath(area));
    It just adds a scriptable object to what I select and it works on other scriptable objects but not on prefabs.

    This should work

    Code (CSharp):
    1.     var area = CreateInstance<AreaDataSO>();
    2.     area.name = "SubAsset";
    3.     AssetDatabase.AddObjectToAsset(area, Selection.activeObject);
    4.    
    5.     if (prefab)
    6.         PrefabUtility.SavePrefabAsset(Selection.activeObject)
    7.  
    After adding an object to the prefab you need to save prefab again in order for that file in the assets folder to be updated.
