Hi! I found that Itch.io allows you to tag games with 2 different variants of Spanish:

• Spanish; Latin America
• Spanish; Castilian (I assume this is meant to be European Spanish, though I don't think Castilian is a super clear name for that)

I'd like to share some links that filter for Spanish as a language, but I don't care which variant they use, so:

• For games in Spanish; Castilian: itch.io/games/lang-es works great!
• For games in Spanish; Latin America: itch.io/games/lang-es-419
• For games in BOTH Spanish; Castilian AND Spanish; Latin America: itch.io/games/lang-es/lang-es-419
• For games in EITHER Spanish; Castilian OR Spanish; Latin America: ????

Is there any way that you could implement some form of lang-es||lang-es-419 key word to put in a URL so it'll show me games in any of those two? It could also work for other tags/categories, like itch.io/games/platform-macos||platform-ios for people who can play only on those OSs, but they don't really care which one.
