Idea/Suggestion-Be able to have zero-gravity fields, or reverse engineer gravity generators

I had an idea for a new block, or button for the gravity generator. What if there was some kind of function that creates a zero gravity environment, in an otherwise gravity heavy/rich(?) environment (such as a small area on a planet where there is an artificial 0g field)? This could be used to construct ships on planets easily, or could be used in raiding/PvP to negate or disable an opponents gravity field on their ship. Though it could mess up the pvp aspect, making thrusters not work in the artificial 0g field would keep players from cheating and using this with a few ion thrusters to get off of planets easily and cheaply. It may not have to be a new block, but an option in a gravity generator's terminal to make it eliminate gravity rather than make it. It would cost about as much as a gravity generator to build (if it were a separate block), but would probably require more power because of it's ability to function on planets. This is just an idea though, and it's not an incredible one. Something like this could break the flow of gameplay, so it really doesn't matter if it goes anywhere or not
