The OP's wish may not be easily possible. If you have the AA sabre booking reference it's not hard to ensure your ff number is correctly entered.
One way to be sure of having ones Frequent flyer number in an AA itinerary is to call AA and ask them to put it in, being very care to ensure they understand it's your

read it back to you (don't prompt).
Repeat until you are satisfied.
You may be able to check if you have either:
- An E-Ticket Confirmation Email from AA, or
- A paper ticket receipt.
The E-Ticket confirmation would have an entry against each segment beside your name. e.g. For a WP:
