Better Stair Customization

I want a way to get the corner versions of stairs all by themselves.

Picture this: Stair A is placed facing north. Stair B is placed next to Stair A but facing east or west which would create a corner stair. My suggestion would be that you should be able to destroy Stair A so that Stair B stays as a corner stair.

This change would not really affect casual players who if they accidentally stumble across this feature could easily destroy the solo corner stair and replace it, but it would be extremely useful and cool for more intricate builds.
