Auto-generate attachments in folders

What I’m trying to do

I’m trying to use automate the creation (or duplication of an existing) file in each of my new folders. Specifically, I want to create a new powerpoint/libreoffice impress slide (ideally one with a pre-defined format) when I create a new folder. That way, i can then open and edit a slide that is already saved in the relevant folder, without having to create and save a .ppt/.odp somewhere else, then drag and drop it into the right place in my vault. Is there a way to keep a slide or other document somewhere in my vault as part of a template, then automatically copy and paste it into each new folder that I create? Can entire folders, and their contents be templated?

Things I have tried

I have used templater to include attachments in my templates, but the files linked in my new note always link back to the original file linked in my templates folder, they are not new copies of the original file in the new directory. I have also tried to use MARP and advanced slides to format my .md notes into slides, and this is not a great solution, I would rather edit my slide in a traditional GUI for presentations.

It might be possible thru your operating system. Finder on Mac has a feature called “Folder Actions” that lets you set actions to happen when the folder content changes. I’m not sure if it can handle this specific use case, or if other OSes have something similar. How to attach an action to a Mac folder for automatic workflows | Macworld
