Ability to put functions and structure files in folders.

Would love to see the ability to put function and structure files in folders for better organization within add on packs. Currently all function and structure files can only be in there respective folders otherwise they don't work within the add on pack. This creates a mess to go through when creating an add on with many of these files and can be a waste of time having to search through the files for the one you need. You can however semi organize them by naming the files in certain ways so things appear together in the list but it would go a long way if they could be organized into folders, within the structure or function folder, similar to how blocks can be organized with folders.
