Workflow - overlaying changed FDX back into Scrivener

Hi there,

i have a feature film screenplay broken in acts and sequences in Scrivenner. I compliled and exported the work in Final Draft. I am now wanting to import back the changed FDX file but so it overlays the structure i currently have. I have created a scene by scene checklist in the Outliner, with where the story moves character, plot and theme forward so I would like to continue using this to compare my revised draft.

How do other screenwriters/novelists deal with importing back revised drafts? Or is there a quick manual method. I guess splitting the FDX in scenes again, importng into a new folder and then dragging, dropping, and deleting, is one option but looking for a neater work flow.
