There is an automated tool of some sort called something like Mix’n’Match which apparently does it, but I’m not sure how many people are fluent in its use. I’m certainly not. As far as I know, only one person has ever used it to do the mappings. No idea how much work is involved in doing it, or their receptivity to running it again, which still just gets you back to the baseline of today and then it starts building up with unmapped stuff tomorrow.
