You can rotate each page by factors of 90 degrees, but at the moment, rotating pages by an arbitrary angle is not supported. The reason for this is that a number of things become significantly more complex when rotating by a value that is not a factor of 90 (that's why many apps don't support that). For reference, to rotate each page individually, tap the "Settings" action at the top of the song editor and change the "Apply Rotation" to "Current Page Only".
I'm not sure if I'll be able to support that feature... I've wanted to implement an automatic deskew feature, but that's fairly complex as well (as it basically involves the same kinds of calculations). I think the only way it would be possible is if it's a destructive action, meaning that, unlike the normal rotation feature in MS Pro, it will rotate the actual file itself so that I don't have to do any crazy calculations in MS Pro. For a PDF, this would mean overwriting the original PDF with a new one that I would build (which can potentially increase the PDF size a lot and make it slower to load as the PDF library I'm using for that isn't great at optimization).
