Restart after editing the conversations?

Hello,
I’m dabbling a little bit in Voice Assist.
When I inserted the following in the “configuration.yaml” “conversation: !include conversation.yaml”.
This also works so far.
However, if I now change something in “conversation.yaml”, I have to restart Home Assistant completely each time for the change to take effect.
It is not enough to reload all the YAML files.
Shouldn’t it actually be enough just to reload the “Conversation” yaml?
Greetings Monika
