Notifications only for specific folders


we’re using NC for a while now and recently a colleague requested to be notified when a folder changes.
Activity app is installed and activated and the colleague ticked the mail and push notifications on “A file or folder has been changed”.
But now he’s complaining that he gets too many notifications because a lot of files and folders change throughout the day.
Is there an opportunity to limit the notifications to only one folder (and its sub folders) or a list of folders instead of all?

Thank you,
