Bing announced you can now request ad exceptions on ad rejections on the whole group level, as opposed to individual ads.
Here is a screen shot on how to specifically request the ad exception at the group level:
It is about 5 clicks but you can select all the ads in the ad group at once.
Bing said this makes it easier to request exceptions "in one easy swoop."
I guess this is one of those feature requests advertisers have been asking for.
