This is a simple problem, but I can't find the solution.

I have a Hierarchical dimension, with consolidate and simple itens.
Some consolidate itens have a calculations (like sum, multiply or divide), and some have not.
The consolidation itens, who haven't calculations, I need to input data (like a simple itens).
How can I input data in consolidate items in a hierarchical dimension, without loss the data inputted in the leaf?
Thanks for any advice.
