Add/update Campaign level audience association in Microsoft Advertising Editor
Campaign level audiences can be added or associate using Microsoft Advertising UI. In Microsoft Advertising Editor, you can only add or update Ad group level audiences.
The feature is currently in pilot and should be available to all before sep 2020.
We often layer audiences onto our search campaigns so this functionality is much needed. It will save everyone a lot of time than going through the UI to add audiences for each campaign. A copy and paste function for audiences on the UI would also be helpful.
