Question about married segments on Suites award tickets for this route.

I want to fly JFK > SIN, with a long stopover in FRA (I'm based in Europe). I understand there is sometimes more availability for JFK > SIN than FRA > SIN.

Example:

Date A: award space for JFK > SIN, only waitlist for JFK > FRA and FRA > SIN.
Date B: award space for JFK > SIN, only waitlist for JFK > FRA and FRA > SIN.

In the above scenario, if I wanted to fly JFK > FRA on Date A, and FRA > SIN on Date B - would I be able to confirm the award straight away without waitlisting?
