No howl at all here. Having no idea what is possible or how much trouble it would be, I have a suggestion. I wonder if you could lift an entire branch of a run-on post to create a new post but leave in its place a kind of url that would take you to that new post. I like the little flow chart thingy at the bottom of each post so if you go to the newly created post from there you'd be less likely to miss anything.
