Clone a line
Open the menu at the end of the line's row.
Choose Clone.
A clone copies every setting. The original line stays as it is, and the copy appears in draft with Cloned added to its name. Click into it and change only what's different, such as the ad product or strategy.
Next step: Edit a cloned line for online video.
