Customizing a CRUD Resource?

[nmalinoski]

Is it possible to customize a CRUD resource? It's very convenient to create a resource, where it automatically creates routes, screens, breadcrumbs, and a menu entry; but I would like to build on that and just customize its Edit Screen. Unfortunately, I don't see anything in the documentation about doing this, just "it’s easy to switch to using the platform", with no elaboration.

Is it possible to override just the Edit Screen for a Resource, or do I have to reimplement everything in separate screens in order to do any customization?
