On selected screens, such as a grouped network, static routes and other places where you may be adding/editing MANY ips etc, I request a toggle from individual fields to a text box where you can copy/paste.
On my old Juniper routers I would routinely grab a set of “blacklist IPs” from an anti-hacker site and paste them into a “block these idiots” rule.
It had a few hundred subnets in it, so listing one at a time is just not practical.
Also, adding a comment field (or # followed by comment in the text box view) is helpful since you end up going “Why am I blocking or allowing this particular IP?”
