I'm not sure of any way with Auctiva..but that doesn't mean there isn't.
I do know that you receive a free 30 day trial with Sellathon with your subscription to Auctiva. And that third party service offers much of the information that you've asked about.

I know for certain that Auctiva deos not have such a feature.
