Yes! You can decide to advertise for example:
- Rental 1 on all channels
- Rental 2 on all channels except HomeAway
- Rental 3 only on Booking.com
As you finish the "Get Connected" checklist for each website you want to work with, you will have 2 options "Connect my properties" (meaning all of them) or "Choose which properties to connect". If you click on the later you can choose which properties you'd like to activate on the channel.
Also, you can deactivate any property at any time from any channel of your selection.
