How can I insert a line break in Dawn 10.0 image_banner headings?

[LIVINGSIMPLY]

Is there a way to put a line break in the headings of image_banner sections in Dawn 10? For example if I want

Good Sleep Starts Here, it typically will have the 3 words, then the second, I want to be able to type two words then the break, or three words, break, whatever looks best for the banner.
