Regardless of that, the dashboard screen has my A and B service reminders setup (by mileage) so I will be hitting the 13,000 mile intervals with services (aka oil changes). If a year goes by before the 13K interval, I will bring the car for the A or B service in early. Assuming all this, should I be all set with oil changes?
Your dashboard screen is set up for max 13k miles and one year. Depends on the car but at least when one year starts to approach before 13k miles have been driven since the previous service, the car tells you "service within x days".
The fact that your car now reports miles to the next service (this is how I understood from your comment), means most likely that since the previous service the car has been driven more than at a rate of 13k miles per year and then it counts miles to the next service (that would hit before the one year limit).
Those A and B services are perfectly sufficient for engine oil changes, no additional changes are necessary, not even good (another debate, at least completely useless) for the engine.
