Hi M, yes anything is possible but to find out a bit more, can you send a cross-section detail? I may just be able to get you an infographic or a tutorial link.
My initial response is to simply create a material in either the
multi-wall type or the clad wall, you will notice in the latest version of PlusDesignBuidl you can also use an existing material and name it as you please.
You could also associate a recipe and add a thermal value or an R rating.
