PowerBI how to change total in table to average

I have a table on powerBI that automatically generates a row of totals at the bottom. This is irrelavent to my data, and was wondering if there's a way to have a row of averages instead? All the answers I've looked up so far is to average the raw data but it is the last (summary) row I want changed

Thanks in advance!
