Is it possible to insert a single body of a multi-body part into a assembly without creating separate files for the bodies?
Using hide bodies doesn't work as each instance of the multi-body part will have the same hidden bodies.
Create a different configuration in the multi-body part with all but one body deleted for each body, and then insert that specific configuration into the assembly.
Its not a elegant solution, but it works.
There's nothing wrong with using configurations, but using display states would be another option. It's not quite as easy to control which display state is being using in the Assembly, but you'll likely have smaller files.
