I was curious if its possible and searched for a bit. I found the same question here http://forums.nexusmods.com/index.php?/topic/147954-geck-setting-conditions-for-reading-a-note/ but unfortunately no one had the answer out of five replies. Looked around on beths geck site but found nothing there. I personally hate the standard notes and don't use them. What I do is make a message instead and type my note there. Then attach onactivate script to a paper note object, book, or holodisk object and have showmessage idnameofmessage in the script. In the same script I set the stage for the next stage. When the object is activated the message with the ok button pops up right away, and after ok is clicked you see your stage update. If the note's content is needed for further reference the script can also include adding the actual physical note. I realize this doesn't answer your question. If you find the answer on your own please add it to your post, I wondered the same thing myself at one point.
