Importing Stories and Backlog from a CSV Excel Sheet?

Hey all,

I'm currently setting up GreenHopper for use across our scrum teams and am trying to find a way to import our user stories and backlog into GreenHoppers database. So far, the only import functionality I've come across is for the importing of issues into JIRA as opposed to the importing of stories/points/ranking etc.. into GreenHopper.

Any help or insight is appreciated, the last thing we want to do is manually enter it all!

Cheers,

Ben
