Not exactly. Are you willing to do something different to complete the actions in this project? One could cobble up a small Applescript to be launched from a toolbar button (or as a keyboard shortcut with Keyboard Maestro or the like) which completed the action and set the start date of the next action according to your policy. I'll point out that you might want the start date to be the following day if you're planning to use the OmniFocus for iPad/iPhone Forecast view and you are finishing the current task late in the day — while there is a section for incomplete items with due dates in the past, there is not a corresponding section for start dates, so a start date 5 minutes before you knock off work for the day would be little different than no start date.

Why do you want a start date on every one of these actions? Do you have a start date on all of your actions?
