Broadcast to a specific node?

I have several nodes running each subscribed to the same topic but I want them to only listen to topic published by a node intended for them. (I’m working a swarm system)

What I want is a bot to listen to only one node which is controlling it. Since ros broadcasts all bots are listening to all broadcasts in same topic.

Can I specifically broadcast to a single node in the same network?

Sorry if this is a stupid question. I’m quite new to ros
