Hello, 
I would like to know how is it possible to add materials to different variables of the same defined group ? 
Indeed, using    " *GroupMaterials, groupId, variableCode"    allows to assign different materials to a single variable, but is it possible to assign a material to different variables of the same group of materials ? In other words, define a material for the top face thickness, the core thickness, etc. of in one group. 
Thanks a lot.
