Hey Ansh A., sure appreciate the help.
Imagine you have a bunch of events and each has a custom property cityID or something similar. I want to take a csv of a list of cityIDs and filter for events where the cityID of the event matches up to one of the items in my list.
So if I have events from New York , Austin, and Chicago, but my CSV only has New York and Austin in it, we don't want to see any events with Chicago as the value associated with the cityID property
