Hm, i don't think you can have different length/depth/levels on the branches.
One thing you can do is to create your own categories and apply a rule in them so that the next level is the same as the one before:
- Mammal
- Dog
- Labrador
Cat
- Cat
Lets say you have the following categories:
- Level1 (mammal)
- Level2 (dog,cat)
- Level3 (labrador)
Then you would create a new level3, lets say level3_new 🙂 and do the calculation:
if level2 = cat then cat
else level3
In the cross tab you will have all levels but for cat you will get the same value for level2 and 3, might help you 🙂 ?
