So if I choose "Case A", the document looks like

I want "Test step 3" to be number 1.3. Is there a simple way to accomplish this? This happens in many locations throughout the document, so I'd rather not have to do a bunch of somersaults with manually changing/re-sequencing the heading numbers all over.
