I have a workaround for that. If you go edit passenger details in the CX PNR and attach an AA FQTV, wait a few minutes then log into the Aadvantage account. You will now see the AA segments in your AA Profile complete with the (different) PNR for AA. You can change seats there, go log back in via CX and out back whichever FQTV you want.
