Sharing the Python libraries created by cx_Freeze between executables for different platforms

Question

I need to integrate a Python program as an executable in a Matlab application, and this should work across platforms. I have managed to do this using cx_Freeze. I now have two folders, called exe.linux... and exe.win..., which each have a folder called lib of roughly the same size and with mostly identical content (lots of .pyc files for various Python modules).

Is there a way to only have one lib folder which is shared by the executables for various platforms? It would save a considerable amount of space, as my applications needs to use packages such as numpy and scipy, which are now included twice.
