This FR already exists. Syntax to delineate end of inner heading section, thus defaulting to next highest

And these ones might be somewhat related with possible workarounds in the discussions:

So I’m going to move yours to help for now. You can check out those other discussions. Otherwise I encourage you to give some examples of what you’re trying to do, and why it’s a major obstacle for your specific workflow, because someone might have a good suggestion or workaround for you.
