Hi,

I want to set a custom slot in my custom NLU component, is there a way to do it?

No, however, you could create an NLU component that does entity extraction and then configure a slot to automatically be filled with your entity.

Slot setting is done in the Rasa core dialogue management, not as part of the NLU.

You can find our docs on creating a custom NLU component [here](https://rasa.com/docs/rasa/api/custom-nlu-components/). You can also find example source for several existing entity extractors [here](https://github.com/RasaHQ/rasa/tree/master/rasa/nlu/extractors).
