The commands mostly duplciate what the users can do from the UI so the operations are visible and the views redrawn.
Moving things without the user seeing is a bit nasty for the user, but are you saying that you want to perform some external operations and then refresh the views with the result i.e. to prevent screen flickering and the user seeing each individual process happening?
There are no commands to do this at the moment but they can be added.
Let us know more about what you want to accomplish.
