Can someone tell me whether we can apply filter on list of values in the 'Value Prompt'? e.g. I have a value prompt (named city) and the prompting is holding around 2000 cities but I want to apply filters on cities so users can select only 15 cities out of 2000 and then run the report. Users should be flexible enought to select any 15 cities from the list. Is it possible. Please advice!
