Nested entities in Board View

I am working on priorities and time allocation today and considered a view that allowed me to see active tasks, grouped by parent tasks, further grouped by project and in columns by company would really help.

The most complex nesting available right now is limited to the list view, but in this case, it would be helpful to see the companies as separate columns.
See how the list view is configured below. Just image this but the two companies are side-by-side
