Thanks for this wonderful module

Hello Infojunkie,
Thanks for this wonderful module. It seems so powerful and most likely this time I'll be able to use it in one of my live project.
I have one question about its features. Does sheetnode let you filter the result rows?
Say I have an address excel sheet, which includes one city column. If a user wants to see addresses of a certain city can he filter the results ?

If there isn't a straight forward method, I was thinking of taking this approach

• Create feed of the main node
• fetch the feed of main node in a different node (PHP)
• displaying rows based on the criteria chosen in this new node.

Suggestions?
