I like this answer. Cursors are found by right clickin on the graph >> visible items >> check cursor palette. Now that the palette is visible, you can enter a name for your cursor to activate it and you can position it with the location numerics. I imagine in your case, you will want to set the postion programatically. You can do this with property nodes. Just set the active cursor to 1 (for the first cursor) then set its postion with another porperty.
