Eclipse refactoring like "change method signature" for generic parameter lists?

Question

Is there an Eclipse refactoring equivalent to the "change method signature" refactoring that would allow you to modify the "signature" of a class, enum, or interfaces's generic parameters?

For instance, if I wanted to remove, reorder, or introduce additional generic parameters to a type, it would change the references to the type accordingly and add default values, etc.

Answer 1

Apparently there is no such refactoring, because the enhancement request I entered has been assigned.
