Topic: Changing the caption every so many pages

Good Morning,

I am in need of creating a slideshow with about 400 photos and the issue is that when clicking next with the arrows on the left side, every so many pages I need to change the caption to the next category of products. Of course it would have been much easier if I could create a slideshow for each category, but I was asked to have them all together.

I am using SimpleViewer through Lightroom, is there a way to create it through Lightroom and then open it in Dreamweaver and add different captions throughout the slideshow?

Thank you,
