What dynamic strategy allows flight scheduling of dynamic creatives?

Start and end date scheduling allows you to define specific date ranges for different creative variations within a dynamic creative. This means you can schedule certain creatives to run during promotions, holidays, or specific seasons, and then automatically switch to other creatives when those dates pass. Weighted rotation, while a dynamic strategy, controls the frequency of creative delivery, not the specific flight dates. Campaign Manager Placement ID is an identifier for where the creative will serve, not a scheduling mechanism. Dynamic targeting keys are used to match creative content to specific user segments based on data, not to schedule the creative's overall flight dates.
