How to add FixedPage to Package?

I create FixedPage and want to add it to Package.
I can add PageContent to PageContentCollection. However, I cannot set FixedPage in PageContent.
How should I do to add FixedPage to Package?　Or, cannot I add FixedPage to Package?
PageContentCollection^ pageContentColl = fixedDocument->Pages;
IEnumerator^ pageContentEnum = pageContentColl ->GetEnumerator;

for(; pageContentEnum->MoveNext() ;) {
PageContent pageContent = gcnew PageContent ();
// add fixedPage to pageContent..
pageContentColl->Add (pageContent);
}
