How to extract two different output documents from 1 master document?

[wimvanrompuy]

I have 1 master document describing all the procedures of my (small) company.
Some of them are applicable to my employees (E),
other to freelancers (F), and some to both groups (EF).

Is there a way to 'mark' text parts as being 'E', 'F' or 'EF', in order to create two final output documents:
* the first (E) with all the procedures for the employees,


* the scond with only the procedures for freelancers?

Thanks you for your answer.
