Windows in parallel walls

[g r a n t]

Hello,

Searching has not turned up an answer for me on this one. 

I am involved in a lot of residential renovations.

Exterior walls are either older solid brick masonry or wood frame construction. What usually happens is the main load bearing walls are to remain while existing interior furring is demolished and a new furring assembly installed (improved insulation, cavity for services, etc.). This can happen on the exterior also with outboard insulation and exterior finish layers. 

What I would like to be able to do is create several wall composites that can create the existing and new wall assemblies and be assigned to either the renovation filter with: Existing to remain, existing to be demolished or new construction. The purpose is to be able to create existing, demolition and new construction plans for the builder. 

For now, I have been doing this with multiple wall composites. What I find challenging is the window and door tool will only insert into one wall. This means I am created a hole / wall opening for each door and window in the additional wall composites. 

It would be wonderful if you could, say, group composites so a window tool will work it's magic and cut a hole in all composites, apply the trims etc.

Am I dreaming? Is there an easier way to do this?

All the best and thanks, 

Grant

I think that if we could separate the skins of a single wall into different layers, as in VectorWorks for example, there would be no need for this. The problem is that we have to create several walls in order to manage certain visibility settings.
