They can only do this for you if the request is 2 months in advance. I think the Sept. 22 should be fine but they may not be able to do the others. When I did it in June, I sent them email one day at a time. They actually emailed me back saying I needed to try again as my request was more than 60 days out. You can email them to inquire about your request. I usually receive their reply within a few hours.
Good luck!
