Multi disc games on RGH?

I have a couple games that are multi disc (Wolfenstien the new order, splinter cell black list, ect.) and was wondering how can i get them to become one?

i want to be able to have it so when FSD Scans the paths, it doesn’t pick up the game more than once in the Games section. that way there is only one picture and link for the game to launch with. also so i do not have to switch the game since i feel like that would be a pain on RGH

I’m not 100% what you are asking…

Do you want to know how to install Multi-disc games or do you want a method to combine a game?

To my furthest knowledge you use the architecture of the games name and the subfolders for each disc label disc 1 disc 2 and so forth
