Broadcasting AssetBundle on SpriteAtlas

As described in the documentation https://unity3d.com/fr/learn/tutorials/topics/best-practices/assetbundle-usage-patterns

So... Let's say you have a SpriteAtlas referencing thousands of icons in dozen of different folders.
Have fun flagging them all with the same AssetBundle, right?

Free tool to do that, select your SpriteAtlas and run it;

Code (CSharp):

1.         [MenuItem("Tools/Asset Bundles/Broadcast AssetBundle")]
2.         static void BroadcastAssetBundle()
3.         {
4.             AssetImporter importer = AssetImporter.GetAtPath(AssetDatabase.GetAssetPath(Selection.activeObject));
5.             string bundle = importer.assetBundleName;
6.  
7.             foreach (string path in AssetDatabase.GetDependencies(AssetDatabase.GetAssetPath(Selection.activeObject)))
8.             {
9.                 importer = AssetImporter.GetAtPath(path);
10.                 importer.assetBundleName = bundle;
11.             }
12.         }
