Is it possible to book each award flight one by one to get the "perfect" itinerary for the same amount of miles for pre-set flights? For instance, want to go RDU-SMX/SBP but when looking at UA.com, it routes RDU-many others-LAX-SMX/SBP. There is a non-stop flight from RDU-SFO but doesn't show unless I go route by route. The ideal routing would be RDU-SFO-SBP.

TIA and sorry if this has been answered. I searched but couldnt find.
