Issue with font auto resize vs text wrapping

I have a question/request that involves the option between having the text auto resized to fit on the screen or automatically wrapped onto the next line.  Is there anyway to have this option either be theme dependent, or be able to have songs handle things one way and custom slides handle things another.  I ask because at our church our paster usually has multiple quotes each week that I enter in as custom slides.  For these slides it doesn't make sense to have the option set to auto resize the font because I end up having to automatically put in line breaks, which is much more of a hassle than it's worth.  On the other hand, I'd rather have the font be automatically resized when displaying songs so that each line of the song fits on one line on the screen.

Is this at all possible, or if not is there any chance it will be added in as a feature in the future?
