String_AGG, or some form of it, is clearly a built-in function that has not been made available to users in calculated fields. Example, when you put a field that’s in the quick filters into a title or group and Tableau automatically creates a list of current values separated by commas and truncates the list with “and x values” after 3 values. I want to use that list in more places, decide if I want “All”, and at what point I want the list to truncate down. Not only would this level of control be amazing in titles and captions, I especially want/need this to get more use out of sets where the dashboard end user can select from a list and it show in the viz their selections so any screenshots for reports are more streamlined and document settings for replicability.
