Auto Sort Birth Order

I'd like a button added to the "change birth order" screen called "auto sort". When used all siblings with birthdates would then have their birth orders sorted by birthdate. Those without birhtdates would sort to the bottom of the list.

If you think this would be a good feature please vote for it clicking the "Me To" button on this link: http://help.geni.com/entries/20777023-auto-sort-birth-order
