The community forums are mostly manned by other hosts and not typically researched for requests/feedback, @David1473. Hopefully they will see your request.
Unfortunately, your situation is really unique. The vast majority of host/co-host relationships are for different properties, not the same one with 2 different listing types. Most hosts would have have giving you the heads up that this was going to be an issue with coordinating calendars and that it would need to be manually handled. That being said, I understand what you want, but I don't know if Airbnb is going to spend the time building that out.
On the other hand, in my opinion, you are making too much of the reviews and superhost status that you both have. Since you are most concerned about the female-factor, close the listing under your own name (or better yet, just snooze it indefinitely) and have your wife add you as the co-host to her properties. Then add the 3-bedroom suite to her profile as a "new" and in the very first line of the listing say: XX and David have consolidated their listings. All the awesome reviews for this 3-bedroom suite property can be found under co-host David's profile. People can click through to your profile and then see all the good reviews you've earned for that 3-bedroom suite. (You will, however, lose the extra benefit of earning 2 Superhost bonuses every year). Also you will , when a woman is searching for a property, your wife will always come up as the primary host, so they will feel comfortable booking with a woman.
Good luck.
