Other sites like Airbnb for a host to list ROOM only? Any suggestions?

I am also listed with Trip advisor / turn key for my room .., VRBO & homeAway is for the entire home.. Not for rooms. FYI G

I really like the co-host feature of airbnb and can't seem to find anything like that for trip advisor.  Does anyone know it is exists? My husband and I manage the rentals together and it's really helpful to see the message flows.
