Is your feature request related to a problem? Please describe.
When building elevators, Contraption Controls are essential to picking a floor. However, there is only 1 style it comes in and is made to be with the other Create Mod style.

Describe the solution you'd like
It would use maybe 2 blocks, 1 for the body and 1 for the frame. It would be nice if I could click on the frame or body, and it would only change the frame or body, respectively. It would also be fine if it just need to be shift-clicked to change a part.

Describe alternatives you've considered
I've tried using other copycat blocks to sort of mask the other sides of it, but due to the unnatural shape, it's impossible. The front is also straight up impossible because you need the front visible to use it, and it would have a gap.
