Ben,

We are handling this requirement by putting shading over components not
installed for a specific variation.  We do all the documentation within
FABLINK and a drawing part is created for each variation.  This is still a
 manual thing but for now Mentor tools do not support multiple variations.
 On the assembly drawing there is a note stating that all shaded components
are not installed.  There is no list of components on the drawing as such,
the parts list provides this information.

Hoping that this may be helpful
