new changes only for an XML to an AAF

X2Pro can only process what FCPX provides as an XML file so unless FCPX can export only changes as a separate XML this is not possible and I do not believe that it is possible with FCPX

I've searched online. Scoured the Apple Help Menu. I've asked an Apple help care specialist on the phone. I can't find the answer. So I'm hoping that Marquis Broadcast might have a solution to my problem.

Is the following even possible?

I must learn how to give my "new-changes-only" from my fcpx 10.4.5 film project to a Pro Tools sound editor.

My sound editor has asked me for only my new audio edits in my next AAF for him. He wants only the new changes which I made at the correct timecode in the film--but without all the existing audio--so I guess it would be with blank space or GAPs filling in all the rest of the film where there weren't new changes for the exact length of my film.

I hope I've explained my problem clearly enough to answer. It's hard to explain.

Thank you for any ideas in advance!

P.S. I'm meeting with him on March 25th, so I must have a solution prepared.
