Hi Rasmus,

Thanks a lot, this really worked. I'm wondering whether this technique can be
generalized to using subtree property :EXPORT_OPTIONS: for any #+OPTIONS
settings? I wasn't able to find this in INFO? Has this been documented there?

Thanks,

York

Use the :EXPORT_OPTIONS: subheading options.

Probably in ox.el or ox-latex.el depending on what you have got in mind.

I don't understand this part.  The documentation of ox-koma-letter.el is
at the top of the file.  There’s also a tutorial on Worg.
