Hello, I own a parcel of land, and I want to try developing it in several different ways. Can I make it one way, say version 1, save it, then clear the land and build out version 2? I want to be able to access version 1 and version 2 of the land. Is that possible, or are all changes permanent, meaning that for a given parcel, you can only see it the way it currently is? thanks becky
