Yes, that could be interesting. Thanks for all the work!
Now if you want to trace that data back to the .shp files, you may want to use the WinSPMBT\Game Data\Design\WINSPMBT_MasterIconList.txt list file, where icons are grouped according to file and icon number.
This file is pretty useful too for finding a single icon, e.g. using
your reference file for correcting the last loopholes that were left behind by Don's latest icon batches! (if there are some left, I'm not that sure)!
