Editor's name two ways

I have a commission to write for an OUP book, and the bibliography
format requires that when listing Edited Book, the (first or only)
editor's name appear as LAST Name, First Name. But when citing a chapter
in an Edited Book as First Name, Last Name. In setting my Output Format
in EndNote I cannot figure out how to getit to treat the editor's name
in two different orders. Any suggestion?
