When you look at a series, you see a “Request Game” button. When you press that button, it brings you to the normal request a game section in the support hub. I think that what should happen when you press that button, is that it will bring you to a custom request a game for that series, and series moderators can accept/reject these games. But, I think that only certain series should have this feature. Mainly the Roblox series, Webgame series, fangame seires, Custom Content seires, etc.

Yes, that it can be changed like the community website

i dont see that this shouldnt be a option for all series with moderation.
