[Zope] Confera - Message order

[Scherer, Bill]

I'm swamped with other work and figured somebody must have done this
already.
How can I reverse the order of the message display in Confera's index_html?
By default, the oldest message is on top, the newest at the bottom.  
I would like new messages to appear at the top.
I imagine I can pass a parameter to the tree sort method, but what?  
Also, I image that this sorting would have to be at the top level only.

Thanks

Bill
