Nothing like that exists. But mainly because it's quite a finite feature that not everyone would have a use for. If it's a one off import, look at other import plugins and amend the data to suit your structure. Repeat import would be a little more work I imagine.
Thank you @a_5mith, that's what I imagined but I think it's worth asking before putting some energy in that :).
I'll follow your advice and take a look at other import plugins.
Regards.
