Filtering dimension selections

Is there existing functionality to facilitate the filtering of a dimension input metric, say on a Department dimension, whereby subsequent selections would then be filtered based on only valid intersections that apply?  I currently have two input metrics, one by dimension Department and the other by dimension Position.  Is there a way that when the selection is made for Department, say “Accounting”, only the relevant Job Positions are now available within that dimension drop-down, so that something like Job Position “Legal Analyst” isn’t a viable option?
