Olle, this is possible. By default, all content types are rendered with a default rendering control both in view and edit mode. You can override this by creating your own edit and/or view controls (.ascx) where you can decide exactly how you would like the page to be rendered and what values to show.
It's not very complicated but a bit too long to explain in a good way in a forum post. I will create a new screencast next week where we show this can be done. I will post on this thread again when its done or check out the screencast section sometimes i the beginning of next week.
