RENDER SELECT VIEWPORT

There is a way! You can render these cameras by setting your comp to the camera you want to render and going to View > Create Camera from 3D View or choosing Create Camera from 3D View in the camera list in the Composition window. This will create a camera in your timeline matching your preferred view, which you'll see when you switch back to Active Camera. You can create multiple cameras from different views and animate them or cut between them like any other cameras.
