Notification when someone changes timeline/date

I wish to get notications when someone in my team changes an agreed finish date for an item.

So i tried using “When a column changes, notify someone.”.

BUT with this automation I do not just get a notification everytime a column (finish date) is changed, I get a notification everytime a finish date is created, even when new items and their finish dates are created…

SO - Is it possible to only give me notification when someone CHANGES the date and not when a date is made for the first time?
