Notifications for task assignments from others ONLY

I’ve setup an automation for when an item is being created, it automatically chooses the person who created it and makes it the item’s owner.
So, when I create a task for myself, I obviously don’t need to get a notification for it. However, I’d like to receive a notification if somebody else creates an item and then assigns the task to me. Is it possible to differentiate those two? Right now I can either have all or none.
Thanks :slight_smile:
