Here is another option but it isn't very appealing because it would take a lot of time and it severely limits versatility.

You could create a theme for each song and set OLP to use themes at the song level. Then create a graphic to serve as the theme for each song and include the vertical title on the graphic. Then create a theme with that graphic and set the text to be right justified. Finally, link each song to their respective theme.

As I said, this severely limits versatility because you would have the same theme every time you used that song. I only suggest it because maybe that is what you are doing currently and this would be a way to do the same thing with olp.
