Hi Kyane,
I don't currently have any plans to import Auctioneer data, but I'll definitely consider it for a future version.
That said, it's actually pretty reasonable to start with a clean slate. After a couple scans, you'll generally have a pretty good set of data for everyday use.
In fact, since prices change so much over the course of a month or a year, the most recent data is by far the most valuable. AuctionLite's data points actually fade out with a half-life of about two weeks, so even if you did import all of your data, it would be supplanted by newer scans within a few weeks anyway.
Cheers,
Merial
