How can the configuration files be separated in the configuration.yaml file?

[engmohades]

I have 6 devices, including kc868-16t and kc868-server, and I will be using kcs-v2. I will use Home Assistant with MQTT. However, the number of lines written in the configuration.yaml file is too long.

 Is it possible to write separate configuration lines for each device in a separate file?

config by one file, 6 devices all config by one file is no problem.
