Oh, now I understand better what you want, thank you. Short answer: No, there is not presently a way to include the Current Handbook in the Events List grid.
For a future enhancement though, I have a question: Would it be enough to only display the Current Handbook as a column in the Events List grid and not include it on the actual Event Dialog? (like the Phone, Email, Gender, Grade, etc is now for example) Also, would you need the Percent Complete too?
