Event to change level

I want to implement a loading screen between every level change I make. I have made a simple scene with a background image and a "Loading" text. My idea is to load this scene first and afterwards load the desired level.

The problem is that I don't want to create 10 scenes for each level transition and since I can't do something like Application.LoadLevel("LoadingScene","nextLevelname") I won't be able to know what Scene name to pass inside the LoadingScene.

I want to know how to do this using events. I want to fire up an event passing the Scene i want to load as a parameter. Then , inside my Loading Scene I will call Application.LoadLevel("LevelNamePassedByEvent").

PS: I do not have the PRO version to use LoadLevelAsync.
