Is there a way to create multiple terrains that use the same settings? (eg textures, grass wind settings)

I would like to make a few small terrains where I can test different lighting conditions and experiment with my art style. If I make changes to terrain settings, eg, adjust the wind settings for grass, I would like that to be actually reflected in all my other scenes that use terrain.

At the moment, the main problem I see is that I can't find a way to change the 'terrain data' of a terrain. If I could, I would just prefab the terrain object and change the data depending on the scene.
