On PBE with the new Dragons we should know the 3rd dragon in Champ Select

So I played a PBE game last night to see the new dragons and stuff as a jungler and thought it would be really nice to know what the 3rd Dragon would be in lobby while doing picks (no bans on PBE) because certain map changes make certain champions better and others worse and it would be nice to be able to play around that fact before going into the game.

For example, a champion like Rengar would really like Ocean for his 3rd dragon because it means more bushes and more room to jump around. However, if he gets infernal it gets rid of bushes and makes him very sad.

So in lobby if you see you are gonna get Ocean as 3rd you can either aim to ban or pick him and if it's infernal you pick something else.

I know this will probably never happen as Riot likes that little uncertainty and not knowing how things will go before the game, but I feel a lot of the community will want this implemented once the patch goes live in 4 weeks.
