3dx - Replace Physical Product within Physics Sim is possible?

I am importing SolidWorks parts and assemblies into 3dx and utilising the update feature of the SW connector; this is a good workflow when making incremental changes to the geometry.
In circumstances where a substantial change is made such as an additional part is being included in the SW assembly, then this is not so appropriate. I don't believe that the SW configuration can be utilised within 3dx.
I wish to reuse much of the connector definition from the FemRep and the established Scenario definition; swapping the Physical Product would be most convenient means (within a duplicate / clone sim) to compare performance of design configurations.
Are there other means of reusing parts of a Physical Simulation?
