Export Fluid Sub-domain as a new part?

Hello,

Does anyone know if it is possible to export a fluid sub-domain as a new SolidWorks part? It would be a very efficient way of creating a new part from the inside of a complicated assembly. I cannot find a good tool for this in SolidWorks that works well for complex assemblies yet (combine -> subrtact is tedious for my application).

Thanks!
