I am not sure if it is still the case, but a few months ago, you could contact Airbnb CS to request that your listing/s be added to (or removed from) specific categories. CS would then review the request and it was at their discretion to decide either way, but they were supposed to let you know either way within seven days.
I did this and all three of my listings were added to the three relevant categories within 2-3 days. However, I should warn you that it did nothing for my views or bookings. My views actually went down after that!
One of the moderators here also stated on the CC not long ago that only a small minority of guests search using categories. Once guests enter in dates and a location, the categories disappear and they are back to the regular search.
