Well, yes and no.
Whole idea of posting this was that regular flyertalkers may benefit from knowing those commands by themselves while dealing with not-so-competent travel agents.
AFAIK some ticketing agents do not know how to insert two or more frequent flyer cards into one itinerary - I have asked them to use SRFQTV UA-SKEBBXXXXXXXXX/P1/S2 command and always successfully credited different flight segments to different programs.

But maybe this is too abstruse - my limited English does not help also.
