I have modeled a fabrication part that requires many parts to be welded together. But I want to be able to call out on my drawing the BOM for each individual part. Is there a way to get each modeled feature to show up  on the BOM chart? I am trying to eliminate the need for an assembly due to the fact of the amount of parts that would need to be created.

I have thought about creating a configuration for each part but I cant think of any way to  "call it out" in my BOM chart.

The main question is, what would be a good way to call out many parts in a non-merged single part file.
