A work around for having the same document open on two differnt pages in two different windows would be this: save doccument twice with two different names. I.e scheduling calls 1 and 2. Then you can open 1 on one page and 2 on another. Bad workaround I know, but should work.
I don't have mine yet so this is speculation.
