work with booking

hello, i would like to work with booking.
I have a big house for 12 persons. The habitation  already exists and has very good comments but the inscription was made by a location agency and i don't want to continue the collaboration.
Would it be possible to change the administration of my house in booking's site or do i have to create a mew one? In this case, i would like you to transfer my comments please.
Thanks in advance
