Exclude workers who already have a Person Category Journey

Summary:

Hi,

We previously assigned a Person category journey to specific workers using HDL. Now, we want to assign the same journey to a group of workers using the Directs or Organization selection type on the Journeys page.

The workers we want to assign the journey to are included in the Directs and Organization of a person. However, some workers may already have been assigned the journey, so we want to avoid duplicating it for them.

Is there a way to exclude those who have already been assigned the journey? Can we use a fast formula to exclude those who already have the journey?
