I have a couple questions about Automatic Product Mapping by UID.
1) Most of my products have the same name. After I register a feed PT maps all of them by identical names. So I added a unique field - "UID" and tried Automatic Product Mapping by UID but still get the same result.
2) Can I set up Automatic Mapping based on several fields? For example if some products have the same brand, name and category then PT should map them.
3) Each time I update the feed files, PT cleans all existing products and the old pages with brands, categories, etc, that are no longer exist in the new feed will respond with 404 code. Is there a possibility to keep them alive?
I was thinking of some "extra" feed that contains all of the fields I need. And set up PT to show some message like "There are no products in stock" if there is no more feed but "extra" one.
