Highest & Lowest

Hi I am using sportspress for darts and we have best leg (number of darts for a leg) that we need to select the lowest from the events data and highest checkout where we need to select the highest, and use that data in the player lists and player stats.

Is there a way of doing this automatically via the configure area equation? as currently it just adds them up when adding more than one match.

Cheers

James
