Importing JournalSpace backup into WordPress

I’m one of those affected recently by the demise of JournalSpace. I was glad to see that it was picked up by WordPress, however, for some reason I cannot find any way to import my JournalSpace backup journal into my new JournalSpace blog. It seems that on the import page, none of the options give you that choice. Does anyone know a way around this? Is this a feature that is going to be added?

Thanks
