How to append multiple values to a multiple value parameter through actions

I have a visual representation on a map where each point corresponds to a location of a client. My objective is to be able to click on multiple points or cities and add each selected city to a parameter that can hold multiple values. I will then use this parameter to filter a table containing information about all our clients. The goal is to display a list of clients located in the multiple cities I have selected.

I would like to clarify if this functionality is currently available in QuickSight. Could you please confirm if my understanding is correct and if there are any additional details you can provide?

Hi @Zhanqi

I don’t believe this is possible.

This looks like something actions might be able to do but I but actions usually will change a value, not add multiple values together.

I can mark this as a feature request!
