Can you make a single multi configured part BOM in SW that looks like an assembly BOM?  Or can I make an Assembly and merge multiple Descriptions?

Ideally I want to merge common "Descriptions" and have the different Lengths ("Length 1" & "Length 2") of those Configurations next to each other... see below... Better still have that coming from just one part see 2nd screen grab. Yes I know I can move the Assembly off the side but I still need to merge the descriptions if it is possible.

Assembly like BOM from one Part?
