Rahsspy server/client

Hello,
Yesterday i installed rahsspy server/client.
The server is on rpi 3b and the client on rpi4.
My hass is on a different rpi 3b.
The installation wored as charm and after a couple of hours i managed to control some light.
Now, i was wondering how can i pass to the server witch client is passing the intents? On snips i could name each client with a unique siteid. Is it also possible on rahsspy?
Thanks for any help
