In Scenes Editor, you can create new scenes asset or modify existing asset in similar way as described in Graphics Editor. Prior to creation, an asset type property "ETXS" must be defined in the "Type" properties.
After the scene creation, it's possible to set the related asset as Not ok to broadcast, selecting the proper flag, below the asset properties.
NB: The asset code can be changed after the creation.
WARNING: When saving the scene, the saved thumbnail would be copied to the scene folder.
