How to deploy templates to entire org?

Hi,

I'm looking for a way to ensure everyone in my org always have the latest verison of our PowerPoint template(s) available directly from within the app.

For sure, we can add the template to a content type in SharePoint and it will be available from the "New" button in any library. But several of our users just refuse to work in SharePoint and wish to have the latest template (or Theme) available directly from PowerPoint.

I know you can add default templates manually, but that is not what we're after, but rather a way to push out the latest version to all instances of PowerPoint that is being used by anyone logged in to our tenant.
