At the moment you can create spot elevations reporting from a specified level. But you will have to specify the level for each instance. I would like to be able to specify the level as a type parameter, because a lot of my spot elevations are based on the same level. Others are the again based on different levels. The solution would be to make a type parameter called "Specified type level" where you can set the level for this spot elevation type, and another parameter called "Use specified level for each instance" as a "yes/no"-parameter type. Then you could satisfy both situations.
