AutoCAD Inventor :: Export Structured BOM View With All Levels

I am looking for a way to export the structured BOMview from Inventor to either Excel or Word. That’s all good and I can do that but I struggle to find a way to include “All Levels” of the structured BOM view. At the moment I use a “For Each item in BOMview” loop to cycle through the BOMView items.

I have also set the StructuredViewFirstLevelOnly property to False. The For Each  loop does not pick up any items inside sub-assemblies.

What would be a nice way to drill down and get an item output like this:

1
2
2.1
2.1
3
4
5
5.1
5.2
Etc.
