I have a number of very wide datasets in Power Query - hundreds of columns each (don't ask). I am trying to determine if (how) to assign columns to display folders programatically. I have access to some data that I could use to assign the display folder based on the column name. Some research into the metadata functions in M is tantalizing but I have not found the silver bullet example yet. Has anyone attempted this?

I've done some basic research and written some bits of M to look at the metadata functions, but that's about it. I was hoping someone might have the magic function call needed to set the display folder, or know if it is even possible.
