There are very few fields that show in both a resource view and a task view. You could use the Initial field and then add the Resource Initials field to the Task Usage view. As long as you as not using the Japanese version of Project, you can also add the Phonetics field to the resource sheet - and then add Resource Phonetics to the Task Usage view. It will carry the phonetics data back to the task row.
