Accordion 2nd window of defined apps

[DarthImriel]

This may already be possible, so if so, please let me know how.
I'd like to be able to define an app or window in some way and have it set that if I have more than 1 Window of it, that it joins with the other window of that app, and sets itself to accordion mode.

Use case would primarily be meeting clients such as Teams, Zoom, etc. that spawn calls and meetings in a new app window. Rather than it tiling itself in the workspace or using an window-detected callback to set it as floating, it would be nice to have it join-with the other window of that app, and then set the layout for that leaf to accordion. I've been doing this manually via joins and layout swaps with binds manually each time and it works well, but doing it via a window detection callback to have it happen automatically would be great.
