Aside from the default slideshow at the frontpage, I created another instance of JA slideshow by duplicating the default slideshow and giving it a new name. For the new slideshow, I referenced a folder as the source of the images (assets). Then I published it to a different page. However, I noticed that any modification I made on any of these two instances always affect the other. For example, if I remove the navigation thumbnail from the new instance of JA slideshow, it will also affect the default slideshow. If I modify the transition effect on the default slideshow, it will also affect the new instance. It appears that they are synchronised to each other, which I do not want.
My website is on a local machine, so I cannot give you any link for demonstration.
