Is there anyway to use the visual class designer to create a class based on a cursor,dataenvironment.

The reason I would like to do this is:
1) If we can visualy represent the classes we have made (like in the class browser) it is much easier for other people to understand my classes.(you can see in one second what parent a class have)

2) I already made a library of classes and I would like to keep all my classes in one file.


Maybe there's a trick for this.
Maybe you can make a custom class that's sumulating or wrap a cursorclass or dataenvironment.
