When making random planets, stars and moons crash into each other and creating some fragments and making from that a random system I wondered what about saving multiple objects as 1 object, If it is possible you'll be able to save entire solar, planet and moon systems. With this feature you would be able to make some crazy things happen in the simulation. For an example what if our solar system was right next to Kepler 186?
It would be great if this got implemented.
