Hi Jarek,
It’s possible but unfortunately it’s not a core feature. I tried to implement it and turned out that my plugin is too flexible 🙂 It’s hard to specify from what object pull the meta when notification is triggered.
So this one waits as an addon (https://github.com/Kubitomakita/Notification/issues/12) but you can of course add your own trigger and handle the meta you like! This would require some coding, but it’s possible.
