Class structure similar to quick books quicken ?

[Stephen Karl Lohning]

Does gnucash support class structure simaliar to  quicken or quick books.

If it does can it assign a class to a bank account.
This way you can create a hierarchy of financial entities. Each of which 
you can
can create a balance sheet and profit loss statement.
In quickbooks you can create classes and associate them with 
transactions but with
bank account. This means that you can not get it to create balance sheet 
correctly.

What I want to do is

Company A
|
|- company B
|
|-company  C

where I can track funds transfer between B and C and
produce profit and loss statements and balance sheets for A,B,C.
Where A would end up being a consolidated report of B,C.
