I am trying to perform a spatial join that will aggregate about 90 fields using a SUM function.
In the Field Map I get the option to right click on each field and set the merge rule to SUM.
This would be extremely tedious for me to do, especially since I have to perform such a spatial join for 30+ layers.
Is there a way to change the "default" merge rule option to SUM instead of FIRST? How about change the field merge rules in bulk?
Below a screenshot of the fields in spatial join that I'm trying to aggregate, I would need to click through each of these and set the merge rule:
