Well in 2006 are you talkin about cars or the multi industry track itself?
Anyways if cars 1 you need to have cars when you are adding them in surveyor look for rollingstock with icons or LARS or IND that way you know they preset for commodites....
Once they on track click on the " ? " to view commodities set for that car or add if you dont see what you want for it....
The Industries now you do the same to view a settings window which you now configure what you want that industry to load or unload etc......
Note that also pending on which one using you can create a commodity when unloading a commodity to it first etc.......
In driver you have a toggle button to click and choose default or a special load for cars also.........
Another way which I found a little pain stacking but time saving in surveyor is to add commodities to cars in theyre configuration files through the cmp saves time than pre setting several cars in a session.....
May note also that LARS and IND , IND2 dont have some commodities available.... example" grain hp" wont work on IND 2 which I believe is
in IND 2 under a different commodity name....vis versa with LARS....
All data compiled by beta testing so I could be wrong on any given thing that I havent figured out yet.....
