Can I force the Flip C101 to portrait mode without flipping the screen past 180 degrees?

[Android Central Question]

I would like to be able to hold my Flip C101 as if it were a book, with the laptop hinge where the spine of the book would be, and have the display switch to portrait mode. Right now the display will only go to portrait when the hinge is folded back past 180 degrees. Is there a software setting I can access to force portrait mode with the hinge less than 180 degrees?
