Predictable palisade cascade magic

[overtyped]

I have some walls in my base that I want broken because they are now a redundant eyesore, but I fear that the wrecking ball will cause a cascade that breaks the outer walls too. It would be nice if there was a hearth magic that lets you designate a certain palisade piece as not cascadable for like 15 minutes or something. This would give you alot of freedom in renovation.

There's no reason why palisade cascade should be random at all. Just make it break X tiles in each direction while leaving the last one damaged like now for easier handbashing early game.
