Topic: buildgallery.php resets captions in gallery.xml

Hi all.
When I've added captions to gallery.xml and then later run the buildgallery.php, all captions are resetted to none.
I know that buildgallery.php is overwriting gallery.xml with new information, but is there a way to keep the captions so I don't need to rewrite them all the time?
Regards, Isak.
