[Role][Management] Admin from category can only add roles for that category

Hello.

Imagine I have a community server where people plays two different games, A and B.
My server has 3 categories (for text and voice channels). 1- Lounge (a place where all players can meet), 2- Game A place (only for people who plays game A), 3- Game B place (only for people who plays game B).
Also, I have 3 roles, "Admin", "Game A", "Game B".

Problem

I want that user X has permission to give users the permission to Game A. If I give him the Admin role, he can do it but can also add the Game B role to everyone.

Suggestion

Creating a way to create "parallel" roles. For example, I create AdminGameA and who has this role can only give roles for the Game A category. And then create AdminGameB and with this role he can only add roles to users for Game B category.

Final

Why this? I could create different servers for different games but I want the lounge area to be a place where everybody can post random stuff and meet each other (who knows that someone starts to play the other game, for example).

I checked some topics and didn't find any idea like this, sorry if this is a repost.

Hope I was clear enough but if you have any questions I'm here to try to explain better.

Have a nice week.
