Hi
I don’t know tool that does it automatically,
but an editor assistant can do it in two or three days from a copy of the original sequence, or better from the copy of the project.
In one of the the films I consult , the editor assistants work for 3 days and create cut list from the EDL, they convert and check every In and Out points from 25 fps EDL to 24 Cut list.
so unnesting is easy.
