Block imported parts don’t mirror correctly (importing them as dumb solids seems to work OK) with incorrect handing and offset.

Is there a way of getting Rhino to re load the blocks under that parent assembly? On import it does a nice job of rebuilding the assemblies as layers, but if I move those layers to under a parent layer and save the file, then next time I open it, the Solidworks assembly is re created as a layer/sublayer under the top level again, rather than re loading under the parent layer I’d moved it to.I’ve hit a few snags (see attached PDF with some screen grabs): I’ve been looking at using the import Solidworks blocks as linked blocks option as this would be useful to be able to reference material across from Solidworks to my Rhino model keeping the parts up to date.
