I take it you mean your RDI. When you do an RDI calculation just change the figure it has calculated for the value you want and save it. Swapping diets doesn't affect anything else. % are automatic. You can select the items you want displayed, like Fat, Sugar etc from the settings page. 

Check out Diet Doctor they have a lot of videos and plenty of info.
