Does Ford Credit offer pre-buying discounted lease miles before turn in?

Anyone know if Ford offers pre-buying discounted miles before a certain time within your lease term? The deal I’m working is around $21 cheaper per (24) months to go with 10.5k miles vs 12k miles. Basically I save $504 during the term, but if I hit 12k the bill would be $750 for overages (.25). Only a $250 difference, but would be even closer if they offered them a bit cheaper during the lease. I’m starting to think it might make more sense to go with a lower mileage lease in the off chance you crash the thing or don’t happen to use the miles.
