Nextgen Gallery Sidebar Widget for each Page

Was wondering if you can use a different sidebar (like the Nextgen Sidebar Widget) for each page. Ideally one would be able to choose which gallery they would want to post thumbnails in WP in the “Writing” a page step. Nextgen does add a little icon for adding an image from the gallery or thumbnails from a gallery INTO the page body. I’d just like the thumnails to always go to the sidebar instead. Right now the sidebar widget puts thumbnails in the sidebar but they stay the same throughout the whole site. Any thoughts?

Thanks.
