None Using parameterization with G4Vsubtraction

I am assembling a complex object using combination of CSG tubs and cones. I am using the G4Union commands. There is a parameterized repeated volume which I would like to subtract the complex object using G4Vsubtraction. Unfortunately parameterization, as I know it, requires that the logical volume of the repeated geometry be defined first. 
When using G4Union, the CSG objects are not logical volumes yet until after the union after which the new object is assigned a material, position etc. Does this mean it is not possible to use the CSG subtraction/addition functions on parameterized volumes?
