Laravel 5 elixir config cssoutput not working

I am using elixir for some sass compiling, but the 'public' folder is renamed to 'public_html' in this project (convention of our webserver)..

Is it possible to set this public directory globally in my elixir config so I don't have to specifiy it on every elixir function?

elixir.config.publicDir = 'public_html';
elixir.config.cssOutput = 'public_html/css';
elixir.config.jsOutput = 'public_html/js';

This should work but it does not!

Any ideas why?
