Idea Summary
Currently quick picks are static pairs of labels/values. It would be great to treat them like the definition of SELECT lists (shared component, static values, SQL query, SQL Function), of course limiting the results to a maximum (low) number of rows.
Use Case
It can make sense to show the quick picks for the TOP-5 values retrieved by a query, because you don't know such values in advance when you are building the application.
Preferred Solution (Optional)
Quick picks could be dependent on the value of a previously entered item value(s) using the Cascading List of Values approach.
