Importing SECTIONS (not Styles) from ePub Best Practices Sample Doc

I have successfully imported STYLES from the ePub Best Practices Sample Document (http://support.apple.com/kb/HT4168) into an existing Pages document. However, the Best Practices doc also has defined SECTIONS which you can see by clicking on the sections button in the toolbar.

How can I get those defined Section types (i.e. Table of Contents, Index, etc.) into my other document which does not included those?

Thanks,

Jeff
