Why outside if u can use inside page type make page in mysite code with needed fields as holder and then make the page for holder then make the holder template and use the holders children page as a slider item. If also wanna make it linkable then just make the page where u need to link as allowed_children in holder .php file
Maybe I phrased some of my original post poorly. What I want to do is to take the code for the agile carousel ( http://www.agilecarousel.com ) and convert it into silverstripe friendly code. I plan on using it on my Page page type.
