I purchased your plugin and I have about 400+ Products all within 5 or 6 product categories. all have different google categories. I was wondering if a option where instead of check marking (ALL PRODUCTS)…we could check specified product categories. selecting all products within that category to make the xml feed from. this would be so much more helpful and more efficient plugin if i could select specified product categories instead of going through each individual 400 products and specifying what feed the product should go in.
