There is nothing OOTB available for selective replication.
You will need to create a custom process step for this and you can pass the agent id dynamically using dialog participant step (have it as step before process step that does selective replication) so that author can select which agent to replicate to.
Or if agent id's are mapped to some page path then you can configure the mapping under arguments options of process step, something like path1~agent1:path2~agent2 etc
Arguments options you get to see in second tab of process step dialog when you configure the model.
