Add DFFs at both Employee Attendees and Nonemployee Attendees

Hello,

I'm trying to add new DFFs at both Employee Attendees and Nonemployee Attendees, at Expense Report Line level.
Creating the DFFs at Global Segments, the fields appear only at Nonemployee Attendees level, while we need to add at Employee Attendees level also.

Can please someone advise us , how to do it? Or is it possible at least?

Thanks,

Denis
