Right now we have to create and maintain separate campaigns for desktop, mobile, etc.
Wouldn't it make sense to have that integrated into one campaign? It shouldn't be hard to have a single UI that allows us to specify bidding etc. for desktop, then mobile, etc.
Ditto targeting. That could also be segmented within a single campaign.
Requiring users to create physically separate campaigns for platforms and targeting doubles, triples, quadruples our workload. It really makes no sense and is a brute-force approach to something that could be integrated into a single campaign management UI.
