Greeting

I used to use "Qt" inside "Visual Studio" but i decided to try "Qt Creator" on my new project. I see something that bother me a lot and i couldn't find a way to fix it.
when i add existing directory to project in "Qt Creator", Source files move under "Sources" directory and header files move under "Headers" automatically and pro file update as well. The thing is, I don't want to see source file and header files in different directory in "Project Window" and i like to see them in same directory.

Like "source_group" in "CMakeLists" file.

Can you tell me how can i do that?

Thanks in advance
