changing the order of xdrawpages

I am using the XDrawPageDuplicator to duplicate an XDrawPage in my impress
document. The issue I am having is that when you call the duplicate()
method, the XDrawPageDuplicator adds the new XDrawPage into the XDrawPages
immediately after the index of the XDrawPage that was duplicated. I need the
newly created XDrawPage to be inserted at the end of the XDrawPages. Is
there a way to change the index of an of an XDrawPage within the XDrawPages?
