OMP Edited by and Contibutors clearly stated


I am using OMP 3.1.0. I have a request to somehow clearly specify editors and contributors of a book. Here is a print-screen with added info (in red), how it should be ideally:

Do you have any idea how to do that? Or an idea how to present this information - that is the editors and contributors of a book? I have to mention that some editors are also contributors so they are in two roles and should be listed in both lists.
