You can have multiple .cpp and .cu files in your project. Unless you want your .cu files to contain only device code, it should be fairly easy.

For your .cu files you specify a header file, containing host functions in it. Then, include that header file in other .cu or .cpp files. The linker will do the rest. It is nothing different than having multiple plain C++ .cpp files in your project.

I assume you already have CUDA rule files for your Visual Studio.
