Set a prefix for the Dataset item id

[juliewww]

Describe the feature or potential improvement

The dataset item ID is generated randomly, which is not easy to find.
Idea: Set a prefix for the dataset, like TEST, so the generated dataset item ID is TEST-0001, TEST-0002.

Thanks for sharing. May I ask, are you using our experiment SDK? This is likely where I'd expect us to add such functionality.
