Filter For media_upload_gallery_form

[greenspeakmedia]

I recently ran into a project where we wanted to modify a gallery and interject some new gallery options. As such the most simple user interface was to add a new setting to the gallery form on the media upload page under galleris. We would modify the shortcode creation and then override the gallery shortcode function with our own code. The only problem is you can't overload the media_upload_gallery_form function in /wp-admin/includes/media.php

Not sure if a filter option or action is the right one here but I think that would give this area that overriding ability as well.

Having the ability to do this would be not only beneficial for my specific problem but woud give people the ability to really take the gallery to another level without messing up a familiar interface that people are using.
