Sorry guys.
C Mode absolutely exists in final cut, and has done for years.
Any time any editor works with film that is one lit and then subsequently graded, the editor will need to supply a roll order EDL.
When you choose File>Export>EDL, in the dialog box choose your Sorting to be Source rather than Master. This will order your EDL in Source (ie Roll) order.
I love Avid too, but you don’t need EDL Manager as a workaround.
Tom.
