No!
Posting the numbers to your Contest is a process that is initiated by the Commissioner of each Contest, and happens precisely when they push the button to do so.
This cannot be scheduled to happen at a certain time, nor does it magically happen when your Contest fills up, or the morning of the sporting event.
We strongly encourage you to post the numbers as soon as you possibly can, as players are always eager to see what numbers they got and the longer you wait, the less transparent the process seems to some players.
