How do I make an inverted hierarchy (bottom up) in SmartArt?

My basic problem is producing a corporate ownership diagram (using SmartArt)
where each company at a lower level has several 'parents' each having a
share. Normal organisational hierarchy (top dpwn) does not work for this.

You could draw your own lines and boxes individually.
