There is a relatively convenient way to manually edit a footnote (or endnote) and change it to an endnote (or footnote). This is fine for a few notes, even a few dozen. But for hundreds, and back-and-forth between note style (as writers often need to do for submitting the same piece to different editors), this is very tedious.
(The counsel of despair is to bring the document into MS Word which has had this feature for many a long year.)
Serious web-searching has turned up no alternative for LibreOffice Writer yet, though. Has anyone devised a macro, or figured out a way of doing mass notes conversion to foot~ or end~ in a single pass?
I live in hope!
