Sending messages from Master Application to peer(s)

Hello, we are looking to find out if there is a way to send messages from Master application to a specific peer(s). As we can see from "HiveGame.cs", we are able to send events to clients at will without having to go through a operation response. We are looking to see if to see if there is an alternative for the Master.

/// 

/// Sends an event for all clients.
/// 
/// The code of the event.
/// The parameters for the event.
public void SendEventToAllClients (byte eventCode, object[] eventParameters)
{		
	try
        {
		var customEvent = new CustomEvent(0, eventCode, eventParameters);

		this.PublishEvent(customEvent, this.Actors, new SendParameters());
        }
	catch (System.Exception e)
        {
		throw new Exception("Unknown error in SendEventToAllClients: " + e.Message);
        }	
}

As you can see, "PublishEvent" allows us to achieve this, is there something similar to this in the Master application? Thanks in advance.
