Not sure about booking rental cars with AA miles, but when I have used Costco Travel - the booking confirmation has the rental company rental agreement number.
I will go to the rental company site direct and link my account with that specific rental.
I would imagine that if the confirmation from using AA miles for the car has that info, you could do a similar work around.
