Ok so i have spent awhile getting this just right for myself. There is no need anymore for map groups its is now controlled thru WORKSHOP, So i have taken the time to adjust the config,
Where you see in the screen shot, AUTHKEY Change ME , Thats not needed until you go into command line changer and select CUSTOM COMMAND LINE
Now i know the Classic Competitive Command line had just de_dust2 but it still plays in COMP settings, I have done it this way so servers will still start up and customers cann add there own workshop collections,
Now here are a few pics and link to Download the new config
