I'll bet that in all the time they've spent working on this, somebody already thought of that. If they did the software first and it didn't work, requiring a return trip to the dealer,how many people here would say, "I'm sure glad they didn't fix it the first time."?
The reason it takes so long to send these fixes to the dealer is that they try to cover every scenario. They need a fix that works properly at the lowest possible cost.
