Prototypes-Hierarchical categorisation of data

I have a data (about 2000 rows: absorvations and 12 columns: characteristics). I want to create a prototype of hierarchical categories. My problem with the linkage is

1. It creates imaginary nodes, but I want the nodes as part of the data. i.e. all nodes should be part of the data.

2. It is limited to 30 knots. I want unlimited nodes.

How am I supposed to do that?
