static layer on local costmap

Hi, I would like to use a static layer (in /map i.e. global frame) in the local costmap. So when the robot moves, I want the lethal obstacles in this static layer that are also in the local costmap, to be inflated. How do I do this? I know static layers are usually added in the global costmap, but for a special case I want the local planner to access this information.
