Connecting Mongo with PowerBi without using a flattened database

Hi, I'm an employee at a thin film fabrication firm. The tldr overall question of mine is whether there's a way to handle deeply nested /hierarchical/ragged data directly in PowerBi. I've tried a few free widgets for hierarchical data but our data seems too complicated for the widgets. Especially since there is no one schema that truly represents the data, as different clients may require machinery with different combinations of components.

To give some background, I'm working with a Mongo DB instance which contains deeply nested hierarchical data. I've provided an example of the data with the field and values randomized below. So far, to connect to PowerBi I've used the Atlas SQL Bi Connector for Mongo, but I've had to make a "copy" database which contains the flattened version of my original database.

The problem with this approach is that there is this intermediary step of flattening the data every time we update the database. I'm in touch with Mongo support about this as well. 
Example:

    "$oid": "f1e2d3c4b5a697887766554433221100"
