Are there scripted shortcuts for selecting scenes with coloured revisions (or other ways to markup scenes for export?)

When we revise boards, we colour the changed panels and make a list (by hand) of the affected scenes for export to the editorial department. Is there a better, more direct way of flagging revised scenes for export? Is picking them out one by one in the export selection field the only way of doing it?

Likewise, is there any way of expressing revision colours in the caption boxes of a pdf? I’ve tried hi-lighting the text but it doesn’t get exported as color in the pdf.
