How to efficiently model stacked windows (clerestory + main window) in DesignBuilder — building-level insertion?

I’m working on a building model in DesignBuilder that has stacked windows — a main window below, and a narrow horizontal clerestory strip window above (with an opaque spandrel in between). Similar to this example: https://drive.google.com/file/d/13B74GPnkPJk3ue6S8wUBUqgPkXwn1hGC/view?usp=sharing

I know how to manually create these by inserting two separate windows per wall (lower + upper window) — but that’s quite time-consuming across multiple zones and many facades.

Is there a way to define this as a building-level or block-level rule or template — rather than adding two windows one-by-one on each wall? Any good workflow to speed this up — especially when there are 50+ windows in the building?

For context: I’m doing both daylighting and thermal simulations, for jeplus I need this feature to be added centrally (rather than manually).
