Custom Data Type in PowerBI? (Transform - Structured Column - Create Data Type)

Does PowerBI offer the custom data type function available via Power Query's user interface? I can't seem to find it, even though a number of articles describe this function as having been developed originally for PowerBI. 

 

I would hate to have to toggle back and forth between PB and PQ to build the query I need.

    meagain I don't think it is possible in Power BI. I have never seen it.

      These M commands -- which I generated using the Excel (O365) UI -- work when pasted into PowerBI. 

       

      If you check out the screenshot below, the filename column is associated with all of the metadata, which appears on a separate card when you click the filename.

       

      let
      Source = Folder.Files("C:\Users\XXX\Documents\Courses\SQL"),
      #"Created data type" = Table.CombineColumnsToRecord(Source, "Document", {"Name", "Folder Path", "Date created", "Date modified", "Content", "Attributes"}, [DisplayNameColumn="Name", TypeName="Excel.DataType"])

      in
      #"Created data type"
