Changing data source from file to folder

I have an exitsing project that loads data from CSV files, and I would like to change the data source to folders. I created a seperate Power BI project with the folder as the data source and copied that new query into the extiting project's query, replacing the orginal Source, etc. in the query editor.

 

The problem I'm having is I can't figure out how to add the helper queries and the "transform sample file" step of the folder-based project to the original one. These actions arent in the query editor. I'm wondering now if this is even possible to do?

 

Thanks in advance for your help.

@Anonymous yes it is possible, and pretty straight forward, if you share pbix (original file) and couple of sample csv file, will get you the solution.
