Automations Access User Who Triggered

I have a two tables that are linked through automations so that one serves as a changelog for the other. I also have a table that maps Coda users to people in our company (which contains positional information, etc) and I have a formula named UserEmployee that returns the currently logged in user as an entity from this table. Is there a way to use the currently logged in user within the automation such that my changelog can have a record of who made the change (rather than showing that Automation Bot created the row)?
