I'm creating my first map, and have a couple of questions:

1. Is there a way to set the amount/type of resource asteroids at a given planet/asteroid/asteroid belt, or is that determined by planet type? I'd like to be able to control which points have crystal, which have metal, and which have both.

2. Is there an easy way to remove/ad enemy militia to a Point of Interest? Example, if I want my player home systems to be completely free of enemies (while still requiring them to explored and discover POIs), how would I go about doing that?

3. Are there explanations somewhere as to what the default planet type templates include? I'd like to know the difference between an asteroid and a dead asteroid, etc.

I hope this is posted clearly and in the right spot. I'm new to this stuff. Any help is greatly appreciated!
