Unique field to capture different information per employee when they take an offering

Content

Hello,

We have a requirement where a learner takes an offering, and let us say 30 people attend this offering. With those 30 people who are taking the class, each one of them has a "Coach". A coach is someone who is not taking the class, not the instructor of the class, but a coach is there to be a coach.

We do not want the employee taking the class to have to enter their coach's information into a questionnaire or the like because we do not want to give the perception that as an admin we don't know who their coach is -- and could give the impression that the admin is lazy.
