How to set the default annotation font?

This question was already asked before, but somebody archived the discussion before an

answer was provided. See here: https://discussions.apple.com/thread/2013497

I wish I was able to right click on the speaker notes area and say something "Make this font default".

The post above says that it is not possible to do this when the presentation already exists, but

what about new presentations? How do you change the default?
