Giving away region locked games easily

Hello,

I wanted to giveaway leftover games from the paradox bundle and Crusader Kings is region locked. Humble bundle gives the list of countries where the game cannot be redeemed but I don't see any easy way to use that on the creation screen.
I'm I supposed to select all countries, search each country code manually and uncheck it ?

I don't gift often but I can't imagine anyone gifting a lot of games and doing that !
I'm I missing something ?
