Smarten Punctuation of metadata

Hi,

Is there any option to widen the scope of the Smarten Punctuation function, to include metadata?

The (very minor) issue I'm observing is that even though all the books in my library have been smartened, when I create an EPUB catalogue of my library, this catalogue itself fails the punctuation quality check, because of unsmartened text in metadata fields (titles and comments only, I think) of some books.

Thanks.
