I wrote something awhile ago to do something similar: http://ephingadmin.com/spacing-out-scheduled-full-updates-in-collections/
You could use that if you don't care about the random time changing. It will change it to a new random time! Change the query to find collections to: Select * From SMS_Collection where RefreshType = '2' OR RefreshType = '6' That query finds all collections with the schedule a full update box checked.
