"Template Pages"? - Custom Post Types/ACF/Metabox/PODs & GP/GB

I am looking for a solution add make it as easy as possible for our customer to input content.

a simple example could be a testimonial (custom post type) that needs a description, name and a photo (for example ACF - allows easy input without messing up the design).

And use GP/GB to design a testimonial-template that displays the information.

is something like this possible/planned?

thank you very much!
