How to access GameObject[] array in PlayMaker

 I couldn't get the Controls property to accept game objects for the array.  I created a property directly in a script.  After that I was able to drag items from my scene to populate the array.  I then move the items into the FSM Array when the scripts starts.
 
  public GameObject[] Waypoints;
 
     // Use this for initialization
     private void Start()
     {
        
         var array = FsmVariables.GlobalVariables.GetFsmArray("PossibleWaypoints");
         array.Resize(Waypoints.Length);
 
         for (var i = 0; i < Waypoints.Length; i++)
         {
             array.Set(i, Waypoints[i]);
         }
     }
