Ok here's what I want to do. I have a list of 5k blogs, I split into 5 different list. I Run scrapebox with one list everyday. Now next week I will harvest another list of about 5K and want it to be completely different from the first one. The only way I know to remove duplicates would be to merge the two lists and remove duplicates. Now if I do that,I will have a big list but I want to keep the second list separated from the first one.. Any one has a technique (or a SP function that's obvious but I don't know ) to make this happen?
