[Plugin: Feature Slideshow] Display specific pages in plugin

Hi there,
I’m trying to show a specific list of pages in this plugin, and it’s not working. I tried sorting through different criteria, and it’s not working. What I’m trying to achieve is this: I want the list appearing in the plugin list to be the exact list of menu pages (1st level only) in that same order. Is there a way to do this other than hard-cording? Thanks in advance.
