Same question here for News, since news are also pages. It would be great to configure a template/page layout with also custom fields (e.g to display custom properties/metadata). Let's say i want to create a news page for a custom content type "corporate news". Would it be possible to create a template and then map it to this content type and map the content type to the page library in the communication site?
To answer both...it's coming, but not there right now. We're working on the capability to save a page as a template, and have that template be an option in the OOB template picker for other users of the site.
