Hi Jeff.
Your reply makes sense, but there is a real need to at least list the targeting presets so that perhaps we can import them and then re-create that targeting in the lineitem.
The reason is simple, if a publisher has spent a lot of time setting up targeting presets (say for groups of cities in their local country where DFP doesn't fully support their regions), then it will be a pain for 3rd party software to have to ask the publisher to re-input those presets.
We currently have a large international DFP customer that this feature would say a huge amount of work.
