As you have to set up brand exclusions per campaign, this becomes cumbersome if you have multiple accounts or campaigns where you need these exclusions. It's also easy to forget if someone creates a new Pmax campaign.
That's why this auto-apply task will let you create rules to tell us which brand terms should be excluded from which Pmax campaign(s) based on their name or label (or simply all Pmax campaigns).
With preview, we'll flag all campaigns that are missing these exclusions, and when set to auto-apply, we'll automatically add them for you.
