All credit goes to Norbyte for this incredibly useful tool.
@ Norbyte, if you see this, I suggest you start a New Topic in this Forum.
Then you can update the first post with each new version, and not have it buried in a long thread, on the DOS1 mods furum.
This post is just to make it easier for new users to find the latest version, and make it clear it works with Divinity: Original Sin II files.
I'll try to keep it updated, and a link to original thread is at bottom of post
