That would be easier to implement.

What about also allowing 30041 alone?
I guess that already forces you to have a structure selection interface.
Yeah that's an option. I'll have to really knuckle down and figure out how to design/build the UI to make that possible. Flexibility is hard to code.
And opens up bugs.
Maybe the structure just needs to be an Asciidoc field. 🤔 Like "top-level: 30041" or "top-level: 30040", and if they have nothing, then it's default 30040.
