How to pass metadata in rasa interactive

Hi, I am using Rasa interactive(Command-line Interactive Learning. From the command line, I can only type messages. But I need to pass the metadata there! is there a way to pass metadata?

Here the default interpreter in Agent is RasaNLUInterpreter. But RasaNLUInterpreter does’t have this feature of passing on the metadata in its parse method.

so there is no way to make it work? D:
