[Suggestion] Magnet Block
Whenever you find a container you have to grind it on location or bring it to your base with a connector. Wouldn't it be cool to have a magnet block that is like a 1x1 small/large block and/or a larger block as well that looks like a mix of a catwalk and a half armor block that could easily connect grids for transport.
Edit: See images for inspiration what you could make with it. And also the ghost from Star wars rebels which has an magnet on the bottom for containers.
