How to make Xcode connvert ___FILEBASENAMEASIDENTIFIER___ patterns in uppercase

Question

A brief description of the issue. There is a C header file template that has this code as a template:

#ifndef ___FILEBASENAMEASIDENTIFIER_______FILEEXTENSION___ #define ___FILEBASENAMEASIDENTIFIER_______FILEEXTENSION___ #endif 

Logically, it creates the following code when the "SomeHeader" file is created:

 #ifndef SomeHeader_h #define SomeHeader_h #endif 

The challenge is to define these definitions in uppercase, for example:

 #ifndef SomeHeader_h #define SomeHeader_h #endif 

The question is, is there a way to do this? Maybe there is some special function for working with placeholders? Is it possible at all?
