I don't see how that fits the criteria for an expedite. I've never heard of that one.. but good luck.
Separation is not fun, but it is, sometimes, part of the process.
I used the my son's US Citizenship (CRBA) in the Philippines to expedite my fiancé's K1 visa.
Her 1st interview had been cancelled because of a lockdown in Manila. When my son got his CRBA interview scheduled I email the Embassy and requested she get her interview at the same time, actually on the same day.
This was approved because having a US child was a reason they were granting interviews...at the time.
Not sure about things in Ecuador.
Good luck.
