Importing AirBnB or VRBO property listing into Booking


I see that Booking.com says on its partner home page that we can easily import property details from other companies/websites we may already be listed on such as AirBnB for exmaple.

However beyond this mention i cant find any further info despite lost of searching community, help pages and even googling etc, which seems very strange.

So please advise the location of the page/tool where we can do this?

Many Thanks
