Comes up fine for me. Select "multiple destinations", but only enter SFO-OGG 07/30 OGG-SFO 8/8, deselect 2+stops, it coughs up (Edit also works by choosing R/T, it just shows up on the second page always) . Should be on the bottom of second page. This is from Chase Ink, redemption is usually 1.25cpm. Same itinerary will be 1.5 cpm in a personal card CUR.

You could also transfer to United and see if it is even better value there, but yes you won't earn any miles in the trip obviously.
