Yes, you can append examples in bulk to an existing dataset using the Phoenix Python library. The `append_to_dataset` method allows you to add examples from a CSV file or a pandas DataFrame to an existing dataset on the Phoenix server. You need to specify the dataset name and provide either a DataFrame or a CSV file path along with the input, output, and metadata keys.
Would you like more detail on how to use this method?
