100% YES! The second either of us got an invite, we both sent emails to our respective coordinators.
Mine would say something like "Thank you for the invite, I'm looking forward to the dinner and interview. I wanted to let you know that I am participating in the couples match and my partner has not received an interview at your program yet. We would love to coordinate interviews if possible" or something along those lines.
Or "I am participating in the couples match and my partner recently received an invitation. I would greatly appreciate if you could consider my application".
I got ghosted on ~50% of those emails, however there were several times when one of us "coincidentally" got an invite the next day, while other applicants did not get the invite (meaning it wasn't part of a "wave" of invites). Most programs were very receptive about couples matching, but the ones in big cities cared less about it.
