Google Announced Campaign-Level Audience Targeting

Campaign-level audience lists are now available in all AdWords accounts as confirmed by Google on Thursday. Advertisers can now add audience lists at the campaign level in AdWords that will make it easy to measure and change your bid adjustments. Instead of trying to change your bid adjustments for each individual ad group, you can confidently optimize at the campaign level where you’re more likely to have enough data to make an informed decision.

However, if you want to set remarketing lists for search ads (RLSA) and Customer Match audiences at the ad group level, that’s still possible.
