Creating Multiple Intents NLU Data

I’m attempting to add multiple intents to my assistant, e.g. “affirm+ask_why”, and I’m finding the creation of the NLU data to be quite tedious. I’m just mashing together data from the 2 intents I already have. Is there another way to do this, a script maybe that can do this automatically? If not it could be useful to add it in the future.
