No, I'm afraid that is not possible. All the files, including 'included' files are compiled into the .exe.
However, you can use a data file to store the level data.
So then you have the compiled .exe and a separate file that contains the level data.
Later on, when you want to publish your project, you could perhaps use a data packer to include all your data into a single file.
