Part where used in Variant Specification (Product Family)

Hello all, 

assume you created a Variant from a Variant Specification in the Product Family via BOM Transformer and "Generate Downstream Structure"...

Based on a WT Part that is included in the generated Variant: is there an easy way to trace from that WT Part (non generic) to all Variant Specifications in the corresponding Product Family where this WT Part is part of (or even that Variant Specification from which the Variant was generated on) ?
