@Riot Adding more champion bots to custom games

Sorry if this isn't the right board to post this. I'm not sure where I would post this.

I was wondering if it were possible to add more champions in the AI pool when making custom games. There are some champions you can face in normal co-op vs AI games but you can't pick as an option when making a custom game(Sion as an example if I'm remembering correctly).

I don't know what is limiting more champions from being added to the custom games bot pool but I think it would be nice to possibly add more champions into it.
