The ___________ feature in Ads Manager enables you to run the same campaign at two different times over the holiday season.

The Duplication feature in Ads Manager allows you to create an exact copy of an existing campaign, including its settings, ad groups, and ads. This is ideal for running the same campaign at different times, like during distinct phases of the holiday season, without having to rebuild it from scratch. Export allows you to download campaign data, not replicate campaigns. Reporting Table is for viewing performance metrics. Multi-campaign is not a standard feature name for this specific functionality; while you can run multiple campaigns, the tool for copying one is Duplication.
