Hi There - In a single select list I am fetching user information from a REST API. Is it possible to have two values appended to the label so that it’s easier to identify the correct option? E.g - I want to show the name in a list and their could be multiple people with the same name. If I can show something like - Fullname suffixed with email and the return value will be the employee id. I have all these columns selected in my rest, not sure how to append it if it’s possible.
