I now realized, that it is possible to set a heading in the reference link and then still be able, with another ‘#’, to directly select all subheadings and so creating quickly a unique path if necessary.
This is the functionality I was looking for and I agree that right now it covers all the usecases.
Maybe it’s just me, but this functionality didn’t occurred to me, probably because Obsidian conveniently shows me all the headinglevels at once. Do you think it makes sense to add a hint for that in the documentation or somewhere?
