These artillery turrets are shooting biters, which are getting close to my walls, so my walls are getting blown open. Any chance of adding a setting to control whether they target biters or not? As they are now, the only use case I have for them is if I move to a position so that anything I've built is past their optimal range, then build them in a cluster so that they're all within each other's minimum range, and then don't build anything else in their firing range ever.
