You can have more than one listing for the same address due to:
Multiple rooms in one space (ie. whole venue vs. showroom vs. half of the space)
Different uses of the space (ie. a table at a pop-up market versus the entire space). You can easily add another space under Listings.
Keep in mind, you might have to spend a bit more time making the second or third listing, but you will save time in the long run when you receive more suitable booking requests. Guests will have access to accurate pricing, availability and photos up-front which will greatly reduce the back and forth for extra details.
