If I set up a Table View to use a set of aggregated data (perhaps I aggregate on 2 fields, and set aggregation types on several fields) and then changeto a Graph View I lose all of my aggregations. It would be great to be able to retain the aggretation state of a View across changes in its type...

... this leads on to my oft-expressed (verbally, at least) request for Named Aggregations to work like Named Queries (which border on brilliance - so versatile!)
