Assuming you mean aside from Chloe? There are some places I've seen it as an option, and while most of these are for minor characters or simple exploration scenes there is at least one character aside from Chloe who merits a "heart card" that it can be used on ( although not used right away ).

Shatter can already be used on multiple different characters and is a core ability for the combat system that was released this week, so... yes? :)
