NEW UX: ability to set up combinations of nested dimensions

[CommunityMember126379]

It would be nice if we have a possibility to define combinations of nested dimensions while pivoting custom views. 

Now, for instance, we can show/hide dimension and it will be set for all dimensions above simultaneously

Current workaround is to refer to module pre-defined view, where combinations are previously set by show/hide and saved

This should be doable using a System Module that contains the nested dimensions and a boolean line item that you check for the valid combinations.  Add a line item that references that system module and add that to your view filter.  Manual Show/Hide is problematic with Production lists since they are essentially hard-coded and will not ALM properly.
