I'm looking for the way to create different types of organization in a pipeline.

I will head for "hotels" and "harbors" in the same pipe, but the info I should provide to qualify hotels and harbors are not the same. I would not like to "pollute" the one and the other with information that only concern one type or the other (Example : For hotels, I look for the total number of nights spent, and for harbors the number of boats.).

Any good ideas ? Thanks for your advices !
