Its possible to move the objects out of the way with a simple Setpos command. You just need to get the object ID from within the editor (resistance only), if youre pre resistance you'll need to use the getnearest command to get the object ID. Then you simply setpos it out of the way.
Disclaimer;
Moving objects already placed in the editor is a REALLY BAD IDEA. unless you put them back to their original place at the end of the mission, they will not revert to their original position until you restart the game. Think long and hard about messing up the island, and if its really necessary for your mission.
