when cutting with a bit that has a stickout of 60mm. I should be able to switch to another tool, that has a stickout of 30mm, and fusion should change the z-height by -30mm, the difference between the two tools. all without having to zero the second tool.
zero on the first tool, and then don't zero any tool change after that.
if this somehow interferes with how other features work, then perhaps this could just be a feature that can be toggled on or off.
