Yep, that's pretty much it. I'm sure this would be far down on the list of priorities, but it would be nice to have. The formations would be KOs, right side wedge, left side wedge etc. Maybe have a punt return play where the punt returner ignore his blockers, or have a % chance that this happens. Or a punt block?
This is one of those items that is a high priority on the low priority list :-) I've been wanting to get better special teams depth chart control really since the beginning. The depth chart override is kind of a way you can do it now, but I recognize that this is lacking what you really need.
