There aren't currently options for either of those, no.
For punctuation I think if we added an option for anything we'd probably just want to hide it - right now it's being positioned wherever the OCR engine thinks it found it, but we wouldn't know what the actual right size for any given piece of it would be.
As for crosshairs, I suppose we could add an option to recognize from the left/top edge of the box instead of the center if people ask for it, but with the current recognition from the center I think we kind of need them just so you know what you're pointing at.
