Map method's name as different name for Code Completion

I'm working with ProcessWire (http://processwire.com/) which has hookable methods prepended with three underscores. These methods are called in code without underscores, which confuses IDE for obvious reasons and creates false positives for calling non-existing class methods.

I would like to map all Class::___[method]() as Class::[method] for code completion, code inspection, and other tools/helpers. To be even more clear, I would like to PhpStorm to suggest for Class::___fooBar($param) methods Class::___foobar($param) and Class::foobar($param).

I know I could go around this issue with defining PHPDoc block for classes, but this solution leads me to another issue: when I do CTRL+B to find called method I end up in PHPDoc block, not the method I actually want to find.
