Creating more than one motion sensor zone Gen 2

On my old wired analogue security alarm the installation engineer set up 3 zones for the motion detectors. Overnight whilst asleep we have always had the old alarm armed but we were able to arm it but omitting motion zone 3 which was upstairs on the landing area. This meant that we were able to move around going to the loo or if the kids awoke and wandered around the alarm remained silent. Is there an option to set up the kit so I can be selective by creating then omitting/isolating a zone when in Home mode at bed time?
