We have improved the ad creation workflow based off feedback that we have received. Now ads can be attached to existing campaigns directly from the new ad creation form. Here is an example of adding a new banner ad to multiple web campaigns:
Notice the “Add to Campaigns” field above. Your campaigns for the current ad type are listed in this box, allowing you to select which campaigns to attach the new ad to rather than editing each individual campaign and adding the new ad manually.
We hope you enjoy this update. Happy retargeting!
