Possible to apply retroactive stats in ESPN league?

[amcg]

I'm commish of our league which had an offline draft yesterday. Ideally we want to begin with today's games (Monday), however, it's unlikely that I'll have all the rosters entered in time because of work commitments.

Can anybody confirm that the league commissioner tools can allow me to start the league stats from today's games even if I don't get the rosters entered until tomorrow?
