Hello! I have a 16 hour overnight layover on the following itinerary (all on one ticket):

SQ 185 SGN (1950) - SIN (2255)
next day
SQ 872 SIN (1505) - HKG (1850)
SQ 2 HKG (2340) - SFO (1940)

I think I'd like my bags checked in all the way from SGN to SFO, and I'll use my carry on for clothing, etc., during my overnight stay at SIN.

Will I have the OPTION of selecting my baggage checked to SIN or SFO, will it be checked to SFO, or checked to SIN and immediately re-checked by me to SFO?

I would call the airline but this was an error fare and I'd rather not have too many hands in the pie...

Thanks for your help!!
