Coach support @ UPenn - likely letters for specific schools/programs? Wharton vs CAS vs Engineering

I think the question here really is how much pull the coach has for certain colleges or programs within a particular university. I have wondered the also - like when submitting for a preread do you have a shot at Wharton, Dyson, an Engineering College or should you expect support for Arts and Sciences only for example - understood this is up to admissions generally but I’ve always been curious how much pull the coach has for the most selective colleges within a particular university/how much weight admissions gives to coaches in admissions to highly selective programs.
