Manage Excel Power Query Groups when importing queries with a script.

Is there a way I can programatically manage which groups that queries reside under? I can't find any reference in Excel VBA to the Power Query Object Model.

Inspired by EditExcelPQM, I wrote VBA scripts inside my spreadsheets to import and export  Queries, so I can do all my editing and source control in VSCode. When I import new scripts or reimport existing scripts, they all land in the "Other Queries" folder. 

(Aside from when doing deep debugging with the full scripts, my queries in Power Query simply load the .pq script files and add them as functions using Expression.Evaluate. That way all source code is external to the Excel file, and only functions I have explicitly invoked will return data to excel. This seems to speed excel up immensely, as Excel isn't constantly refreshing intermediate queries.)
