We would all LOVE an application like that. It takes a lot of research in order to find available flights. Trying to get a saver award near the holidays will probably be impossible at this late date.
Your best bet is to try calling the airline and hope you get a good agent who will do a lot of the research while you are on the line. If you can't get a good agent then you will be stuck, like the rest of us, just trying dates, flights, various routings etc.
Good luck.
