Best workflow for multiple wall finish combinations without Composite Bloat

Hi everyone,

I am looking for the best professional workflow to manage various interior and exterior wall finishes in Archicad without ending up with an uncontrollable number of Composite Structures (Composite Bloat).

I have prepared a small demo plan to illustrate the issue. As you can see in the attached image, even in a very small layout, I am forced to create 5 different wall combinations (TYPE-1 to TYPE-5) because the finish layers (C-1 to C-4) change depending on the room types on either side of the core wall.

I have already tried two common workarounds:

Using Wall Accessories.
Modeling finishes as separate, thin composite/basic walls (furring walls).

However, both methods create serious headaches when it comes to doors and windows. The openings do not automatically coordinate seamlessly across multiple walls, and whenever a door/window position or size changes during revisions, it becomes a manual tracking nightmare.

How do you handle this complexity in large-scale professional projects? Is there a native feature, a specific Wall Closure/Opening Tool workflow, or an industry-standard method that makes managing separate finish layers seamless when dealing with doors and windows?

I would highly appreciate your insights and workflows. Thank you!

Operating system used: Windows
