one store, multiple lists problem when using filter

Hi

I have one store that loads a json file with events, fields like eventid, eventname, eventdate, eventday.

My idea was to use this store for multiple lists, each list shows a different event day, so in order to do that I use the filter method on the store. But it seems like that the filter applies to all of my created lists?

All the lists are dynamically added to a panel that has a card layout.

It this method possible at all, or do I really need to create a store for each event day? And wouldn't this cause a performance problem with multiple reads to the json file?

Maybe there is a better way?
