Hi
The "Microsoft Copilot (Microsoft 365): Improved template support when you create a presentation with Copilot" you find was released, and you have found the related Microsoft guidelines as you post in your first thread.
I created a template via following the guidance of the "Copilot PowerPoint Starter Template" from "Keep your presentations on brand with Copilot in PowerPoint".
Then I enter a theme to let Copilot create a new presentation according to my template, it does reuse some layouts.
Like Emi suggested, we'd give the feedback to Microsoft, the developer team will listen to our voice and make Copilot smarter and more efficient.
Thanks for your understanding.
