[Plugin: NextGEN Gallery] multiple slideshows on one page

Hi,

I have included two NextGen Galleries as “Picture Lists” on one page.
On top of both list are Links to start the slideshow.
The Link leads to a page on which both slideshows are running. But I only want the one slideshow running I actually clicked on.

Can I change that? Or better that the specific Slideshow is running in a Lightbox?

Link for the page:

Thank you for your help!
