WordPress 3 global turn off year/month uploads folder

so i just noticed in my wordpress 3 multisite that there isn't any obvious place anymore to turn off the year/month uploads folder. before, you could go to Settings > Misc. The only way to do it now is go into edit sites under super admin. dang stinks. why did they take off this setting? anybody know a way to set a custom default uploads folder for all new user multi site blogs? thanks!
