Hoi,Is there an API for manipulating properties that are set in #+PROPERTY lines before the first headline of a file (i.e., not in a property drawer)?I've got some properties that (a) make sense when set for the whole file, and (b) the file contains multiple first level headings (which isn't going to change).Using org-entry-put when point is before the first headline throws a "Before first headline" error (when when the #+PROPERTY line already exists and I want to update an existing entry).N
