i love the new coupler blocks, they are great. But 2 things about them annoy me. 1: for them to be placed close enough to resemble realistic, they need to be placed a block apart. And 2: they don't actually connect, which is really not visually satisfying with knuckle couplers. So i propose the addition of "Connected" variants that look like 2 couplers in the same block

even better, let us wrench/interact with couplers to extend them a little bit to bring them together
