Filter card results in a dash based on drawing on a map

It would be amazing to be able to filter results by drawing an area on a map.

For instance I have a map at the top of dashboard and several cards below. I draw on the map an area including half of Manhattan and this updates all the cards in the dashboard just for that specific area

That assumes I have of course a lat/long column in all the tables used.

A little bit similar to how we can now filter for a time range by clicking on the beginning and draggin until the end in the chart editor view.

This is currently possible

Did you find a way to do this?

Could you provide more details or step-by-step on how to do it? I've done it on map questions but can't figure out how to do it on dashboards, it doesn't seem possible.
