Trying to use #include with Quill

Hi, I'm writing for a project that involves a number of playtesters who rely upon the permalinks of Quill in order to run through the various scenes. The story itself has grown quite large and we would like to use the #include command inside of Quill so as not to burden the Quill engine with an excessively large program.

Is there a way to insert files into a folder that Quill uses so that the #include command can utilize them when needed?

Thank you in advance.
