Best way to Geo-Block / Can FNT not create a list for Fortigates?

I've been looking at how to best do geo-blocking, and my options are to set every rule I have for inbound access to only accept from specific locations, or to manually add all the ones I don't want to a rule that applies at the top of the list. With SonicWALL, WatchGuard, etc. I can select the countries I don't want and set that policy at the top, why doesn't my Fortigate have the same option?

As for the meat of the question, does anyone have a curated list of countries that they use and is available without a $25/month or more subscription?
