How can I use nlu lookup table in separate file?

Hello Rasa 2.x I need to use lookup table entries. I have 10k+ entries that can be insane to list them inside nlu.yml. I want to know how to use lookup table in a separate file and what format they be written.

Thanks in advance

Look at person_name.yml.
