I've had the same issue too recently... the send event, however, can target a specific game object if you wish to either drag the object directly to it (what i'd call "hard wiring") or you can create a variable and have the object you wish to send the event to be declared either in a previous state or an action that preceeds the send event action. the "game object" section which is the second from the top in that particular action is where you'd want to set the object or the item.
for example, when a monster is being targeted by the player using the "Mouse Pick" action, i place the object that it picks into a gameObject variable. from there i do a test to determine the tag (you don't need to do this, i do though) and if it's tagged "enemy" it goes to the "dealing damage" state where it uses the "send event" to send the global event "dealt damage" to the object that it's targeting.
granted, my own issue was not knowing how to make an event a global event (the checkbox next to the name in the event browser.)
let me know if that helps or if you need more information.
