having some doubts on redemption here.

im redeeming a USA-bkk flight using qf miles. if say my redemption comes up as usa-hkg, then hkg-bkk, is it possible for me to redeem the hkg-bkk 2 days later, is, have a transit/stopover in hong kong for 2 days without having to spend more miles?

thanks in advance for advise.
