Saving customized transform in game

Hey all. I need to know how to sort of make multiple presets of transforms I can save, and instantiate in another scene. For more details, I am making a space combat MMO game. In the ship customization, you can add parts to any existing part, making the ship larger and larger. I would like to know how to save what I have created in the customization scene, and load it in another scene. It will also need to save it's children into the prefab transform.
