Hi All,
Curently, you cannot pause ads with in an adgroup.
For the type or work you are needing to do to your ads, no process with be quick and easy. Here is a suggestion: if you are constantly adding and deleting ads, why not just modify the price in an existing ad through Ace?
Existing ads have performance data that will help with its delivery. If you are adding new ads and removing the old ones, they will each have to build up its own performance data.
Using Ace, you can just update only the ad with the part you want, the save and upload the change and you will not loose that built up performance data.
Hope this helps.
Thank you,
