It would make for less clicks for users, if a report creator could set default values for report prompts.
With default values, in most situations, the end user viewing the report can just click the 'Run Report' button, and the defaults will be used. Currently the default value is '--any--', but for something like a date field, it would be very useful to be able to default it to 'Past Year' or some other value other than '--any--'
