Notes/Domino 4 and 5 Forum

I have a field with names datatype. We pull a group name from the address book. The name is saved in the field. Email is sent to the people listed in the group. Is there a way to display the names in the group within the field (when the document is saved)? The individual names is needed to give editor rights to the document. I tried using @Implode and @Explode but I only get the group name. I see this being done when you send email to a group name. When I look in the sent view and the individual names are there.
