Nextgen-remove bulk opload option from a gallery

I have nextgen set up to allow subscribers to add a gallery and manage their own gallery. I don’t want them to be able to access the bulk action feature as some of these functions affect other galleries. Is there a way to remove the bulk upload or restrict a particular role from using it. Ideally I would like the user to only be able to add images, delete images and edit descriptions on their own gallery.
