Templates in Chooser vs. those in "Import Outline"
 

When I create a new Graffle document I'm presented with a Template Chooser containing 6 templates for Brainstorming, 3 for Organizational Charts, plus a basic drawing template.

When I open an OmniOutliner outline by control-clicking and selecting "Open With" OmniGraffle in the Finder, I'm presented with a dropdown menu containing many more choices than are available in the Template Chooser, including:

Text
Flat
Mini
Shiny
Tabs
Boxes

How can I create a new document from [I]within[/I] OmniGraffle and use one of these templates? I'm using OmniGraffle Standard 5.2.2 on a MacBook Pro.

Thanks for any help with this.
