When copying several plan lines across campaigns, you can use a checkbox to select whether you want to copy the selected plan lines with the existing AdSchedules or whether a new AdSchedule should be assigned.

The plan lines are only copied with the AdSchedule if they run on the same ad server tags as the original plan lines.

If you decide to only retain the structure, each AdSchedule in the selected plan lines will be replaced by a new AdSchedule. Thus, the grouping of the plan lines is retained for the ad server. New tags can then be created for the publisher in the ad server.
