Is it possible to mark some file as "not my code" ?

I don't know if this already possible but I wish that, if debugger can treat external dll by skipping when we navigate debugger, it could be do the same thing on some file in the project

In my case, I have one large C# file that was generated from antlr in my project. And it make the debugger freezing anytime the step going into that file

I don't need to debug anything in that file but I the step need to pass that file so many times, and so I want to ignore any step that got into that file, just skip it like it was not my code

Is it possible?
