Problem creating an Omnigraffle diagram from an oo3 pro file
 

I am trying to import an outline that I made using oo3 pro into omnigraffle. When I open the file it puts all of the sections on one canvas. I need each section to become its own canvas. Do I need to do something in oo3 or something in omnigraffle. Or is there anything i can do besides copy and paste each individual section into a new canvas?
