Setting the default font for Sketch Entity Text on a part 4

I can't figure out how to set a default font for the Tools / Sketch Entity / Text feature on a part. Currently I need to uncheck the "Use document font" in the Sketch Text property manager, then choose the font size, height, etc. that I need. This is getting tedious when I have dozens of text sketches to include. Basically I'm asking, how do you set the default "document font" for text sketch entities? I've tried looking in the Tools / Options but can't find what I need. Thanks, ~Tina
