Structural search and replace: Search for interfaces in class declaration?

[5.1.1708]

I have following code:

public class Foo : IComparable
{
      public int CompareTo(object obj) { throw new NotImplementedException(); }
      public int Bar<T>(T obj) where T : IComparable { throw new NotImplementedException(); }
}


I use search pattern: $comparable$
where comparable placeholder is declared as Type System.IComparable (not derived types).

However this only finds the IComparable used as constraint in the Bar method, not the IComparable in the Foo : IComparable declaration.

Is it possible somehow to make the search (or another structural search search) to also find the IComparable in "public class Foo : IComparable" ?

Thanks.
