Nextgen gallery question

I have a gallery on the url listed above. https://nancycurtin.com/lamp-photo-gallery/
I want to put a gallery on another page which just shows Lampshades. When I insert the gallery into the Lampshades page, the lampshade images appear in the lampshades gallery and also on lamps gallery.
Can’t I create two separate galleries for two different pages?
Thanks.
