Map - can you customise Controls? (range slider on Group By, add bespoke values)

More map questions!

  1. Is it possible to make a range slider use the aggregated metric (from a terms aggregation/right join), e.g. SUM(sales) rather than just sales?

  2. Is it possible to create your own bespoke Controls? i.e. show specific preset values in a dropdown, which cause specific preset filters to appear selected. I basically want certain competitors to appear on the map.

I'm using Kibana 7.7 btw.

Thanks in advance!
