@David11954 If you have 10 rooms you need 10 listings I am afraid. Do make sure they all look different. Also switch on professional tools in your account if you want an easy way to manage more than 1 listing.
Did @Mike-And-Jane0's response help you set up your multiple rooms? If so, it's always a lovely gesture to mark it as the best answer. It's like a big virtual hug to the member who supported you but also to support other Hosts who may have similar questions in the future. 😊
