Is it possible to create a hierarchical exposed filter in views using the Data module?

I’m using Data module to adopt tables from the same DB as ‘native’ Drupal tables and Views module to present the data.

I added two dropdown exposed filters with Selective filter module. It takes all values from fields and puts them to the selective list. It works fine.

However I would like to configure my exposed filters the way that the second filter will show values according to the chosen value in the first one. E.g. if you choose a specific academic department in the first filter, the second one will offer you the list of this department’s staff members.

Is it possible to achieve such a behavior? If so, do I need any extra modules (taxonomy?) or should I create a module myself?
