Lobby Change

Hey, I lag out alot when in the lobby. Because of this I have trouble changing my runes whilst waiting to pick my champion, espesily if I have to change my runes or champion based upon what my, or the other team, picks. I think it would be a nice update if we could lock in our champion without having to exit the rune changes. We already have few pages so it seems clear we should be changing the existing ones game by game so changes to make that easier would be greatly appreciated.
