mailmerge: Is any possibility to change defaut output format?

mailmerge output format i default set to *.odt.
Is any possibility to change it to for example *.pdf?
I was looking for expert settings, but nothing found…
I’m sclerotic or to fast and mostly forgot to change the format … :slight_smile:
