The custom template feature would allow you to create a folder in your current WordPress theme were you build your own layout for reviews. It is very rudimentary right now as I am still in a “wait and see” mode in relation to what WordPress is doing with Gutenberg. As such, there is no documentation for the feature right now.
In regards to a custom template per review, I have never thought about it but it should be possible via an custom extension. I will look into it.
@Kemory,
Does ‘very rudimentary’ mean ‘not yet available to play with’?
By the way, the Novelist plugin has a great template editor. A combination of your plugin with its metadata and a Novelist-like template editor would be the ideal.

“Very rudimentart” as in it is meant mostly for developers and there is current no documentation.
As for a new template editor system, I won’t touch anything like that until WP core releases Gutenberg and its mature.
