Can we declare objects from json monthly ? (AWS changning IP's) on Zywall

Ive a requirement to keep on top on Amazons addition & changing IP addresses.

ie ive recently learned an AWS service can change IP overnight..

I had permitted the IP addresses for the AWS datacentre months ago, but not good enough. I now need to regularly check amazon list for new IPs on "eu-west-2"

So reading this > https://docs.aws.amazon.com/general/latest/gr/aws-ip-ranges.html

Amazon keep a jason file available online > https://ip-ranges.amazonaws.com/ip-ranges.json

Is there anyway to read this & create / amend IP objects in the firewall ?

thanks in advance
