Identifier for unique datasets

[KleinerNull]

This would be an interesting idea, I have prepared a demo notebook with a nasty xml response to parse from amazon ;)

As you can see the dataset fulfillment_order is unique, but still it is saved in a list, just with one element. It would be nice if you can say with an identifier, that that dataset is unique and won't be stored in a list, instead in a normal dictionary.

UNIQUE_DATASET is my proposal for a name for such a identifier.

Otherwise, the possibility to flatten all one-element lists in the output would be also interesting.

Would you provide me with me a mock output showing your vision for this, I think it could be a good enhancement
