So I've got what I feel is a decent understanding of the 'Available Values' part of the report parameter property. I have a working query that is pulling multiple values from a table and displaying them properly. My question is (without altering the database) how can I add another value to the options? Basically if the query is pulling back 'foo' and 'bar', I want to also give the user the option for 'All'. Right now the only things that are being returned from the DB is 'foo' and 'bar', I want just tack on the option for 'All' without changing the database.
