You could create an overload of the function to take multiple destination paths, and all it does it iterate all the destination paths and call the original Copy function:

public void Copy(string sourcePath, params string[] destinationPaths)
{
    foreach (string destPath in destinationPaths) 
    {
        Copy(sourcePath, destPath);
    }
}

You can call this with:

Copy(sourcePath, destinationPath1 [, destinationPath 2, destinationPath 3...]);

or you could just call Copy(source, dest) twice.
