Power to weight ratio restriction in Private Multiplayer

I have seen that we have the option to limit power (HP) and weight in two different options to restrict private multiplayer sessions, but I think it will be more beneficial to have also a the combined power/weight option since now we can see that car attribute when building the cars. For example I want to create a lobby in wich the maximum power to weight ratio is 0.12 HP/lbs. This will make competitive private sessions more fun and realistic.
