Feature Req: Whitelist for Templates

Hi, I was wondering if it would be possible to incorporate a way to whitelist Gutenberg for a specific template.

I see I can do it by Post ID/Slug/Titles and I can Disable it for templates, but in my case where I only use one template for Gutenberg, it’s really hard to manage adding individual post/page id’s in the whitelist section.

Hope this feature can be incorporated in a future release.

Thanks in advance for your consideration.
