ArcGIS Desktop - Need to set Merge Rules in Spatial Join for 90  fields, is there a way to do this in bulk? Change default merge rule?

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:
