I have a selection of ads that I want duplicate. They are all in the same adgroup. After duplication I simply want to change the landing page of the newly created ads. How would I do this in the Adwords interface or in the Adwords editor? When I check the ads with Adwords editor after duplication and changing the final url the ads are removed because they're all marked as duplicates. How would I avoid this behavior?
