Hi Richard Pense,
You are right, these settings did not make it in the 1st version of the Visual Designer and it is not possible to set them via UI at the moment. However enhancements in the designer for such settings are in the process of development and we will have the Backend Configuration Settings released as part of the product in our next weeks internal build. Using the Backend Settings you will be able to control the caching behavior (as well as some other advanced settings) on the model level though the Model Settings Dialog. Controlling the caching behavior per class is our next UI improvement of the designer which will be available in about three weeks.
