eB Layout Editor - Include Document Copy column in Documents Held relationship on Person Object

Hello,

I'd like to add a new column, or replace an existing column, on the Documents Held relationship for Person objects in eB Web. I want to display the Copy distributed. Currently we display prefix, middle, revision, name, date acknowledged, transmittal number, and Class name.

What Data Type and Element must I enter, if this is possible? I tried Data Type: xs:string, Element: copy and Invalid Type for the dropdown selection.

Thanks for any and all help!
