You have to implement a proxy model. It's not that hard (although not trivial in this particular case), believe me.

I have the code that does something like that but I can't show it to you :( I can give you a hint though. Think how to map indexes between a flat model and a hierarchical one. Write down the solution on a piece of paper and then implement mapFromIndex() and mapToIndex() according to your notes. The rest should be easy.
