I noticed that the Photosmash Caption field in the upload form populates the Title and Description fields in the Wordpress library, but leaves the WP Caption field blank. Is there a way to have the form populate the WP Caption field instead of the Description filed?

I ask because I'm using the built-in WP Gallery type, and even though users are submitting captions, the grid of thumbnails doesn't show them, because Wordpress considers them Descriptions.

Thanks!
