Add option to create "groups" for IPs and countries to be used in rules

[maddler]

Summary

Blocking a multiple countries/IPs currently require creating multiple rules for each resource, adding a considerable overhead to manage this, while you are most likely to always block (or permit) a consistent set of sources.

Being able to manage that as groups might considerably simplify the process.

Motivation

This is, mostly, around simplification and making the process of creating and managing resources as streamlined as possible.
A simple process, also, helps to better manage your security posture.

Proposed Solution

Add an admin section to create/manage groups for IPs and countries that can then be referenced in the rules by adding a "Country Group" and "IP Group".

Alternatives Considered

Adding single entries to the rules looks to be the only other alternative.
