Format Paragraph Justified but Aligned Centered

Hello I would like to see if it's possible to format paragraph text justified but instead of the last line aligned to the left, that the last line aligns to the center.

The issue is a lot of the headers of my company's test look best formatted in a centered alignment, but the body paragraphs have to justify because they are large text bodies and this looks the best.  A second best would be if Constant Contact implemented a way to add hyphenated paragraphs.  

Is there a code or possible way to change the justified paragraph to align centered?

If not, can we add that in the features request?

Thanks!
