It would be extremely useful to allow a control object with a date measure be allowed to push the selected value into a parameter and be used to create advanced filters. For example, I have a history table which shows changes in parameters by date. I would like the user to be able to go back in time and show all the most recent parameters on a given date. So the user would select a date, which would filter the history table for parameters <= than selected date, but that resulting table would then have to filter for max(date) grouped by parameter_id.
