At long last, we've completed support for importing multiple Amazon wishlists into PriceZombie.
The interface is similar to what you have used in the past, except that there is now a wishlist drop down on the watchlist page. Select either the default PriceZombie watchlist, or a named Amazon wishlist that you've imported. They are no longer combined into a single page.
You can import as many wishlists as you'd like.
I've also simplified the import screen, so you just need to give it a name and supply the amazon wishlist url.
