So I know this would be a lot of processing power. I would love in the future to be able to set a larger polygons symbology based on an arcade Feature Set expression of other layers.
My use case is to have a neighborhood polygon change status colored dynamically based on all tree inspection points within the polygon. By using an arcade expression to loop at intersecting layers and return a color for the symbology.
The idea is as the trees have been inspected they turn green, once the entire neighborhood has been inspected it would also turn green.
To reduce processing it could be something set to update every 5-30 minutes
