Load same scene twice

Hi,

I'm using LoadLevelAdditiveAsync to load a scene and add it to my main one, and with the purpose of making an "infinite" world I want to load the same scene more than once to then change via scripting the parameters of the objects. The scene seems to load twice without any problems, but I don't know how to get a reference to the objects it contains since they are called the same...

Is this possible in Unity?

To expand on the reasons why I'm doing this: - First, I'm a newbie in Unity. - I'm using 2DToolkit's tilemap and for what I've been reading, instantiating a prefab of the tilemap is heavily discouraged (plus it seems to be somewhat broken). On the forums it's been suggested to build the tilemap in a new scene and load the scene additively. - I want to have a large tilemap that I can modify in runtime and not via the editor nor editor scripts.

Thanks in advance for any help!
