Can I add a staff Notebook to an existing Group?

Hi, I have just started in a new school and I want to spead the love for OneNote!

They have a Group set up for all the teachers but the nattached notebook is untouched.  Is there a way I can convert this to a staff notebook?

This would allow me to show them the wonders of One Note without the hassle of disrupting their group.

Thanks, Martin
