Define #include string for class element?

[Asperamanca]

I have lots of class elements that have (so far) not been generated as code.

When I generate a class, the #include directive pointing to other classes is always wrong, because
a) the class has never been generated, and points to some default filename
b) the class has been generated, but the #include directive should not contain any paths (this is handled by include paths in the IDE)
c) some classes that should use #include <someheader> use #include "someheader" instead

Is there a way for me to define, for each class, how it should be included in other classes?
