My clients are continually adding new ads to their existing campaigns. It used to be so simple to add them and then just sort by "ads with no clickthrough url" and then add them in. I cannot sort this way in NXT. I can't even sort by the pub name, which would also be a little easier to manage. The only way to do this is to either scroll through all of them and find the blank ones, or export it. When I only need to add in a handful of URL's, going to the trouble of exporting them all, just to add 5 URL's is time consuming and unnecessary.
