Hi,
This cannot be done directly from the UI, you have to fiddle with some files on the DSS server.
Look at the structure of folders within INSTALL_DIR/resources/notebook-templates/dataset/pre-built
Replicate a similar structure in your DATA_DIR (thus creating DATA_DIR/resources/notebook-templates/dataset/pre-built/my-new-template-id
Within the .ipynb file, the string __INPUT_DATASET_SMART_NAME__ will be replaced by the name of the dataset on which the notebook is created
