fail2ban Trusted IP addresses manual adding

is there a way to enter Trusted IP list to a file in the OS. I loook at the
/etc/fail2ban/jail.conf
and
/etc/fail2ban/fail2ban.conf
files but no the IPs I entered through interface does not exist, so they are not the right files.

I have got lots of IPs to enter, so any workaround for this?

thanks.
