Can't seem to find how to do this in Forge.  Is it possible to set how many resource asteroids orbit each planet in forge?  I'm wanting to create a map with a couple of sun systems with a poor amount of resource asteroids and a central sun system with large resource deposits.  As a related question how do you set how many resource asteroids orbit in a Asteroid belt or PlasmaStorm.  I know with those two being uncolonizable the astoroids when have to come with a neutral extractor.
