I am having continuing discussions with my TA about the upcoming DONE3.
Apparently when re-scheduling, she must request from one stopover point to the next stopover point. And this is where the question of married segments does arise. Mrs WF's married segment problem (DEN-TUS-DEN) still exists, and the current connection times means that AA disability support had better be on their best behavior at DFW. These are the only segments she is flying solo.

Another reference point results from Iberia re-scheduling our LPA-MAD flight to be under MCT for the long haul QR flight. I think just selecting a better IB flight to replace that is possible (but means the departure time is now 0730). To reschedule the long haul flights to have a more reasonable start of the day apparently will require avoiding married segment issues all the way through LPA-MAD-DOH-KUL.

It should be easier to schedule wandering....
