I have been searching for this for a long time and not able to achieve it without resorting to manual copy and paste from one doc to the other.

This sounds like utopia. :-) Do you have a link to a page that outlines these steps?

It works if you don't change formatting, don't edit the same section, don't rearrange chapters and don't have lots of changes or a large document. You do any of that, and the application crashes.

It's good for a small fix, but not something to rely upon in your main documentation workflow.
