title: Large number of values in a multi-value parameter
body: <p>I need to be able to return data from 4000 customers. These 4000 customers unfortunately must be in the multi value parameter so I can select for example 10 different customers from the list and it will then return its data (with extra filter, so it saves time scrolling up &amp; down). Correct me if I'm wrong, multi-value parameter only handles 1000 values at max, although I can see all 4000 values in the list, it will not return all 4000 (it does in the preview, not after it's deployed). I have tried to skim it down to 900 and it will return all 900. I do understand that it is not rational for a user to tick checkboxes more than that, but I still won't be able to return the rest of the 3000+ customers. What is the best way of doing it please?</p>
