Cross filter hierarchy from multiple tables

Hi, I have multiples tables that share the same hierarchy structure and values. I want to both cross-filter (over both tables) and drill down using the hierarchy. I can't create inline hierarchies from multiple tables, and I can't create a relationship on more than one column. How do I accomplish this?

e.g.

table 1: Action data

table 2: Incident data

Hierarchy in both tables: Region > Company > Country > Division

If I use a slicer to filter hierarchy, all Action and Incident charts should cross filter.

If I click on either the Incdient or Action charts, I should be able to drill down through the hierarchy.

TIA
