I use parameters to build dyanimic hierarchies, however I defined and created the hierarchies, they were not built-in. What do you mean by built-in hierarchy? The only built-in hierarchy I'm aware of is date which has built-in hierarchy based on date part.
Built-in was probably not the best word to use. I'm using the hierarchies you can build into Tableau Desktop (http://onlinehelp.tableau.com/current/pro/online/mac/en-us/help.htm#qs_hierarchies.html ) . I see it is a request to make them usable in a parameter so my question is answered.
That helps, I'm still not sure exactly what you are trying to accomplish. I think your issue might be thinking of a hierarchy as a single object rather than a collection of related objects. Check out this article it may describe what you are trying to do Dynamic Hierarchies with Tableau - Clearly and Simply.
