I have a single filter on my dashbaord that can hold multiple values
i also have pin map.
What i want is that when I click on a pin, a value from this pin (name of location) is put in my filter. so far so good. however. when i click on another pin, it throws away my original value. but I have a filter that can hold multiple values. I want to click on multiple pins and all values are added to my filter.
so first i click 'location1' and then i click 'location2' on my map , i want my filter to contain both location1 and location 2 (which works if i type it). but currently it throws away location1 and inserts location2
