Schedule unique parameter value

[KoayCTeik]

How do I schedule for unique values across multiple columns? 

For example here I have ST01, ST02 for floor finish, then ST02, ST03, ST04 for wall finish.

Can I get the schedule to show me a list that shows only ST01, ST02, ST03, ST04? 

This would practically allow me to quickly understand how many types of finish that I have in the project, and avoid manually checking which number that I have assigned. 

Hope I am clear in my question.

Hi,

So for example ST04 code will only be a Wall Finish?

Create 3 seperate Schedule for each of the Finishes (Floor, wall, ceiling) and group on the Finishes

Is that a Room Schedule?

Sounds to me like you want a Key Schedule.
