In Sage 9 which I’m familiar with, I could create a controller with the name of the Post Type or Template that I wanted to target, for example SingleMyCustomPostType.php and via the soberwp package the controller would automatically load on the targetted custom post type (my-custom-post-type). Then with protected $acf = true; I could enable auto loading of ACF fields to variable names.
What is the equivalent of the above in Sage 11? I did find a similar question asked in Februrary - Middleware/Controllers for the Template Hierarchy? but it didn’t receive any answers?
