Visual Studio 2012 C# - Extend Code Completion to log Full-Qualified Names

I was wondering if there is a way to get full qualified names from items
of the code completion set. For Example if I trigger Code Completion on
"String." I want for all items the type (function, property, ..), return
type, argument list, and so on.
With Resharper I can get LookupItems which represents items in the
Completion list. But they don't provide full qualified names. Only the
display name in the completion list.
My research on visual studio and intellisense provides the following
Interfaces/Classes:
Completion Class [1]
CompletionSet [2]
ICompletionSource [3]
ICompletionSourceProvider [4]
But I can't find the informations I need. Hope someone can help me. Regards.
