So, i came up with the Idea if you build one of this Factory Building than you get the Surface, but if you remove it store it in a Blueprint with that Name and a Factory in it and change the Backer Name to that Name and save it to that like: Factory 01, 02, 03 etc. . I think you can set that the Blueprint cant be open or cleared. And if this is possible you dont need the store in Health Option or you dont have many of them Stackt together.
