Do we have a possibility for nested Cascading list?

[MeenaElangovan]

Requirement: I have four dropdown list (Region, Country, Enterprise, Business) in Feature work item type. When I select Region “NA”, associated Country dropdown should be populated, when I select country, associated Enterprise dropdown should be populated, when I select Enterprise, associated Business dropdown should be populated.

Problem: I believe Cascading is between two fields only. Do we have nested cascading list extension? If not, is it possible to have 2 sets of cascading lists in the Feature Work Item type. That is, One cascading list for Region and Country and another one for Enterprise and Business. Please consider this as priority. I am premium customer for Microsoft Azure DevOps and I need to build this functionality to stand a new team. Thanks in advance!
