@unown006 I'd suggest deleting or editing your post to reduce confusion.
Per the topic: I'd prefer to have something like @CalenLoki's suggestion and have to physically move cargo around if you don't want to do it "by hand". However, looking at how Space Engineers struggles to hand its merge blocks, I don't think we'll see this.
More likely we'll have cargo containers and conveyors. It still requires engineering and usually creates weakspots, but it's a bit simpler programmatically.
