Ability to have container-based targeting for locales

Similar to how page targeting is done, it would be nice to be able to do this for a container element, like a box — container-based targeting. The use-case is that there could be certain content that's only meant to be shown in certain locales. For instance, I might have a banner that's only meant to be shown in the United States, but I'm not looking to have a banner in other countries; it should be completely omitted from other locales, rather than translated. This would help prevent having to duplicate pages in these scenarios.
