Feature Request: Created by to be categorised as people

Let the “created by” and “last updated by” columns by classed as “People” so that we can use that as a trigger for an automation.

In my specific example I want to let me CS Team know when a specific Board Guest has added an item to the board. I don’t want them to be notified every time a new item is added by a members of their team, or other Board Members within the company.
