Who gets complimentary Main Cabin Extra seats?

• AAdvantage Executive Platinum®, AAdvantage Platinum Pro® and AAdvantage Platinum® members
• oneworld® Sapphire and Emerald members with elite status on Alaska Airlines, British Airways, Iberia, Finnair, Qatar Airways or Japan Airlines

I don't care about accrual, so the FFN switcheroo isn't what I'm looking for. Just wondering if people have been able to assign different FFNs to different segments at booking/far out for seat selection purposes.
