Currently the DMX dump functionality always creates a new scene and you can then link it directly to a button, chaser or slider.
In addition to this I think it would be great that instead of creating a new scene you van actually overwrite an existing scene thereby updating it.
Add a new option: Update scene and that displays a list of scenes, you select one and hit OK, the scene is now updated.
