Are UFW IP groups possible?

I have a giant list of IP addresses I need to manage incoming access for. They are also constantly changing.

Is there a way to create a group of IP addresses/ranges for a firewall rule?

That way, when a rule needs to change/add/delete for that group, I can just change the rule, and not have to type in the whole group?

Something analog to:

ufw allow in from IP_GROUP_1 port 443

If not, any tips you have on this are valued.

Thanks!

EDIT: answers for IPTABLES and not UFW are fine.
