Sum value to column data in CSV import

[ecometer]

Ubuntu 20.04 pgloader --version pgloader version "3.6.3~devel"

Is it possible to add a custom value to the one find in a column of a CSV files? Something like this:

HAVING FIELDS (measure_date_time [date format 'YYYY-MM-DD HH24:MI'], measure_id + 2)

Thanks, Paolo
